BA IT systems failure: Uninterruptible Power Supply was interrupted

JamieL

Restore in the wrong direction?

Reminds me of one occasion a few years back. Had installed an active-active firewall pair across two sites with each handling one leg of a 2MB leased-line to the internet (see, I said it was a few years back!) and automatic config hot-synchronized between the pair.

One firewall sends alarms to say fan playing up. No problem, will just power it down, replace with a good unit then bring it back up again. Power down the offending unit, traffic fails seamlessly over to the secondary and all good. Re-cable from dead unit to the new one, power up. Still all good. Give the "re-synch" command and hear someone outside wondering why the internet has stopped working. Upon closer inspection I determine that the re-synch has indeed happened, with the configuration being dutifully copied across - but I now have two units each with a blank config. Heart stopped and blood ran cold as I realise what I've done...

Fortunately it was only a 15 min sprint to the other site where I had a laptop with all the backed up configs. A lesson learned the hard way indeed!

But TBH in BA's case I can't believe that the Friday of a Bank Holiday weekend wasn't considered a change freeze with nobody allowed to do anything other than emergency work in their DCs.

74 countries hit by NSA-powered WannaCrypt ransomware backdoor: Emergency fixes emitted by Microsoft for WinXP+

Kill switch

So, the NSA knew there was a "kill switch". They knew the code had been stolen. But they chose not to activate the "kill switch".

Conclusion: the code was still actively working for them, and now some current "operations" will be affected....

Emergency stop buttons - that unstated weakness

Reminds me of a firm I worked for who had installed so much tech in their building that the power supply couldn't handle it. Never mind, get a big container genny in the car park. And, since the tech is more important than kettles and lights and stuff, leave the computer room on the main power and wire the rest of the building into the genny.

All was fine until some kids in the car park one evening wondered what happens when you press the big red button.... genny winds down, all the doors pop open!

More worryingly, how many times have you driven past critical locations (cell towers, office blocks) and seen cooling fans on the outside with that appealing big red button. Press a few and you can be long away before the kit on the other end overheats and services start dropping.

Hacker predicts AMEX card numbers, bypasses chip and PIN

Re: Payments... At Businesses...

on a recent trip to the US I was amazed that no retailers even looked at the card signature. Just as well really because (in an attempt to prevent fraud should my card be stolen) I'd written on my signature strip "NO SIGNATURE PIN ONLY"

123-reg still hasn't restored customers' websites after mass deletion VPS snafu

JamieL
Alert

...which is why it's a good idea for your Business Continuity Plan to involve as much diversity as possible: different suppliers, different infrastructure. And of course it counts for nothing unless you've tested it, and testing means more than "just spin it up" for a quick "hello world". It means use it. For at least one business cycle (even if just on a sub-set of your business e.g. 5% of customers).

Have just been having that discussion with my current employer: explaining that the scenario test we did on a Friday morning between 0800-0850 may tick some boxes but is not comprehensive and gives no guarantee that it'll still be working 5-10 days later.

I worry about firms who are still naively waiting for a restore

I read the article yesterday morning, and had a giggle. Then later in the day got an email from my sons' school apologising for their website being down and referring to a BBC news story about 123-reg and how it wasn't really their fault.

Three things jumped out at me:

1) I pay them a lot of money (yes, it's a fee-paying school and yes it's possible in this industry to earn enough for that) and am disappointed at the corner-cutting to save a few hundred quid a year

2) That they didn't just buy hosting from somewhere else the next day, get their website designer to re-upload, change the DNS and carry on normal jogging. It's clear by now that 123-reg can't be relied upon

3) Bad performance plus good excuse isn't the answer. They're pretty good at drilling that into the children but are still prepared to try it on with the parents

Met plod commissioner: Fraud victims should not be refunded by banks

JamieL

Its the tradeoff between convenience and risk

I'm less bothered about the temporary disappearance of the few quid that went before the bank spotted an unexpected sequence of transactions (the fraudster testing my card first) than having to do without my card for up to a week and having to re-enter my account details to all the websites that stored them.

...wait a mo... perhaps it's all the websites storing my card details that were part of the problem...

JD Wetherspoon: A 'hacker' nicks 650,000 pub-goers' data

JamieL

Well I'm not surprised

A few months back I went onto their website to book a room. I was on the verge of hitting "submit" when I noticed that the page header was plain old "http://..." and so my card details and address were about to be sent off in the clear.

Being a kind soul I sent a message and screenshot to them via "contact us" to let them know, and in particular draw their attention to their Ts&Cs which said that I was responsible for ensuring the security of my personal details which I clearly couldn't do if I used their website.

Of course I didn't get a response, but then I guess they knew already by then.

Licence to snoop: Ipso facto, crypto embargo? Draft Investigatory Powers bill lands

JamieL

How do they know it's "me"?

In my household there are at least four people and getting on for a dozen devices that access the internet through one ISP & IP address.

How the hell will they know which person they are tracking the browsing history for?

It was hard enough trying to control my sons' access through my router even with fixed internal IPs and firewall rules and OpenDNS... once they knew I was doing it they simply took to leaning out of the window and using the free wifi from the pub across the road!

Although I'm thinking it's a good reason not to have a go with IPv6 where the traffic can be more easily traced back to individual devices...

Safe Harbour ruled INVALID: Facebook 'n' pals' data slurp at risk

JamieL
Megaphone

But will they listen?

I have spent over four years trying to explain to the bosses in our US parent company that telling our UK clients that shipping their data off to the US because it's technically convenient to do so isn't acceptable under EU laws unless the clients (and the respective data subjects) first give us consent to do so.

The standard US response has been "but we're Safe Harbor certified so it's OK". Which bits of "we have to comply with our laws regardless of what you think" don't they understand and will this judgement make any difference? (the answer is of course not - the 'Merkins just don't get and never will get that other countries have their own laws which are preeminent in those countries).

Jog on...

The last post: Building your own mail server, part 2

And take control of your folders

...and if you're into storing mail in folders, set up with IMAP and install POPfile the mail sorting utility. I've had it running for literally years and it sorts all my incoming mail into over 20 folders so I can see at a glance what needs my attention and what can be left until later. One of the best "install and forget" utilities that just gets on with it, learning as it goes.

Does the RSPCA have your gun licence or car registration? NOBODY knows

JamieL
Holmes

Re: I would guess...

Making two very broad assumptions that:

1) Legitimate firearm/shotgun holders would threaten anyone with a weapon when challenged at their front door

2) People who hold unlicensed weapons (the ones that are used in the vast majority of crimes) don't abuse animals and get visits from the RSPCA

Because after all, if the RSPCA "inspector" in his plot-lookalike uniform turns up at your door without a warrant a simple "sod off" is quite sufficient without resorting to weapons of any sort (legal or otherwise).

Lords blast UK.gov's fixation on broadband speed over reach

JamieL
Unhappy

and nobody's truly on the hook for the first mile

In my village we are a fair distance (2-4km) from the exchange, yet the actual speeds achieved vary significantly from house to house, and not in a way that correlates with distance. It also depends a lot on the weather (worse after extended periods of rain) so I suspect that the quality of the copper cables plays a big factor; it's not just contention upstream from the exchange and how your ISP shapes traffic onto the core backbones. I am one of the lucky ones with 5-6mbs but others (some of whom are closer) struggle to get to 2mbs.

But if you try and complain to your ISP that your service is sh*te you just get bounced around and nobody seems to be able to kick BT into actually going out and sorting out the copper so that we all get a consistent "up-to" speed. Even if BT is your ISP you get passed between the various departments and none will take accountability for it.

What's all this "bought" malarkey?

Nah, "proper" hobby computing is when you get the handful of chips (CPU, RAM etc) wire them up with veroboard and wire-wrap to create your own. Not quite an early adopter (early 80s for me) but had to wait until my teens to be allowed to play with such delicate toys.

Write an O/S (hand assembled, natch) then burn onto a EPROM, plug into your machine and see what happens when it powers up.

Whereas learning Latin and Greek

...which were taught in that sort of way definitely helped me learn to program. When I got to uni the course modules on parsing and computer language design were suddenly blindingly obvious - deja vu indeed. If you can parse a "statement" in Latin to extract the meaning before restoring into English then writing code to parse a line of assembler before outputting in hex became suddenly very straightforward.

How can family sysadmins make a safe internet playground for kids?

JamieL
Linux

And they have phones too

Don't forget that most kids eventually get phones and most have web browsers on them. You'll have to rely on their network providers to control what they see on those. Not all come with content control in place out of the box (although Vodafone does), I'm amazed how many parents have no idea what kids look at the the playground these days.

I've got a fairly well controlled home network so I know what they're looking at but I know that'll only last until my boys get their first phone... But I'm going to make sure they pay for their own data plans.

Google explains 'why' ads target user's Gmail

Thumb Down

Who owns the "content"

Looking at Google's terms of service, I'm not surprised. It seems that you give away your rights for all content you put in (e.g. emails you write and send) but Google' recognise they have no rights over stuff inbound to you.

Can't use inbound (but if they do it's your problem to notice and act accordingly):

9.4 Other than the limited license set forth in Section 11, Google acknowledges and agrees that it obtains no right, title or interest from you (or your licensors) under these Terms in or to any Content that you submit, post, transmit or display on, or through, the Services, including any intellectual property rights which subsist in that Content (whether those rights happen to be registered or not, and wherever in the world those rights may exist). Unless you have agreed otherwise in writing with Google, you agree that you are responsible for protecting and enforcing those rights and that Google has no obligation to do so on your behalf.

But you give away outbound:

11.1 You retain copyright and any other rights you already hold in Content which you submit, post or display on or through, the Services. By submitting, posting or displaying the content you give Google a perpetual, irrevocable, worldwide, royalty-free, and non-exclusive license to reproduce, adapt, modify, translate, publish, publicly perform, publicly display and distribute any Content which you submit, post or display on or through, the Services. This license is for the sole purpose of enabling Google to display, distribute and promote the Services and may be revoked for certain Services as defined in the Additional Terms of those Services.

So that's why I don't use it!

What's a 3rd party?

But you see, these guys aren't "passing your data to a 3rd party". They're using a fulfilment agent who aren't technically a 3rd party from a data protection perspective, they're just doing stuff on their behalf.

Now, if that "3rd party" were to do anything with the data that wasn't strictly on behalf of the requestor, well that _would_ be wrong. Like play.com and the firm that was sending out marketing emails on their behalf who had the list compromised.

So, it's up to you to satisfy yourself that not only the firm you give this data to can look after it themselves, but also that their agents do so as well. But of course it's not something you ask when you sign up is it? And they wouldn't tell you anyway.

Libya's internet goes dark as upheaval spreads

JamieL

If all the servers were outside Libya then - yes...

It's true that if the routes to the rest of the world are disabled then Libyans have no access to sites such as YouTube, Twitter, BBC etc.

But that doesn't mean they've necessarily lost the Internet completely - it may well be that internal servers can still be accessed and email is still flowing via any (not government controlled) mail servers.

A slightly imperialist view that people only access or need web services based outside their country: "Fog in Channel, Continent cut off" springs to mind!

Australian companies don’t trust their backups

Unhappy

DR/BCP isn't a one-way exercise either - even if you have got it

Some years ago I worked in a UK govt department. We had what was considered a "mission critical" system with a DR / BCP setup that had a duplicate IT environment across town, dual fibres, switches etc and all transactions on the live database constantly replicated to the backup.

Problem was, although we could (in theory) cut across to the backup system within a matter of minutes (just re-point the clients at network level) there was no effective way to resume normal working on the live system afterwards.

So, whenever there was a problem with the live system I'd ask if my team of data inputters and analysts could flip over to the backup. The answer was invariably "no, because we'd then have to have >1/2 day downtime while the backup is then restored to the live system afterwards" Regardless of whether it was a 30 minute or 30 hour problem, we'd just twiddle our thumbs and wait for the problem to be fixed on the live system.
