back to article UK research network Janet under ongoing and persistent DDoS attack

Publicly-funded academic computer network Janet has come under a persistent DDoS attack today, which hobbled multiple internet connections, including the Manchester to Manchester Core Router. Janet, effectively the UK's computer network for educational and research institutions, first experienced connectivity problems shortly …

I was perhaps under the mistaken belief that academic data exchange (globally, let alone in the UK), was moving to a new "Grid" system that would have massively enhanced encryption and stunningly complex security - perhaps it was all a dream.

That's the problem with academic anything though - looks great on paper, but the reality is usually lacking.

Those that do make it into the real world often end up as over-engineered solutions to problems that don't exist.

"That's the problem with academic anything though - looks great on paper, but the reality is usually lacking."

Yes, good people don't normally want to work for the crappy pay that most academic institutions (or the public services in general) pay. So you get with the less talented dross. That's why they are always spending so much on consultants / contractors to come in and do the hard stuff.

I would say it's a fair bet they will eventually be paying a network contractor / consultancy to block this attack...

Might be an idea to ask Twitter nicely if they could have IP addresses of anyone repeatedly refreshing the page today.

Not sure if serious?

I know of at least 5 people that have been doing that legitimately, trying to find information about the recurring outages!

@Anonymous Cowherder - You're right, it was a silly idea. And would prove nothing even if you could find a suspect.

Hmmm, someone forgot to do their homework and thinks that by taking down Janet it'll give them an extra day. So, won't be arts, language or classics students. Wonder what Man Uni specialises in churning out?

A certain Steve Furber is working on a 1,000,000 ARM core Silicon Brain in Manchester.

Maybe the brain is starting to become self aware? Skynet, anyone?

I is one of them computer engineerz.

Though we were more interested in getting that new fangled Telnet working on our PDP-11 at the time. Janet were but scribblings on a white (possibly even black) board ....

Some interesting historical notes here:

Though there was internet - just not as we know it.

That took me back; I wrote code for X.25 PADs and Switches - the history missed out Green Book - which defined the PAD.

Mighty big DDOS attack

Must be a huge attack to take out a network with a 100Gbit/s backbone ?

If it is a private network how hard can it be to isolate the points that are being attacked and limit connections in order to protect the rest of the network.

I'm a noob at attacks of this scale.

Would be nice to see an update on the front page.

Re: Mighty big DDOS attack

It's taken out a router. You can either overload the routing logic by sending more traffic than it can handle, or, if you craft your traffic correctly, you can force the packets to go via the CPU rather than being handled by the switching ASICS.

If it is a private network how hard can it be to isolate the points that are being attacked and limit connections in order to protect the rest of the network

JANET doesn't exist just to link UK Universities (& other institutions) together. It also exists to link UK Universities to other institutions. i.e The rest of the world.

If you cut JANET off from the rest of the world, you'll end up with a lot of *very* annoyed researchers. (And admin staff & students)

And IT staff who can't do anything because both our email and ticketing system are hosted off-site!

Can't they just walk the data down the road on a USB stick?

The Mancester to Manchester Core Router doesn't sound very far to me. Is it on the tram network?

It depends how gridlocked the trams have become at Picadilly Gardens.

I can sort of understand why people attack Governments and businesses but why would you attack an academic network? It's like kicking someone puppy.

I think we should drop the leading D in DDoS. Why? Because who launches a DoS attack that isn't distributed now? In fact could you even realistically launch a non-distributed DoS against any target that would make the news? I

not just academics that use Janet

UK wide local government uses Janet as it's connection to the outside world. Our connection is still flakey in the extreme.

The only news site I seem to be able to get to (apart from this one of course) is the National.

Obviously the work of deranged nationalists.

That's sure to be the headline in the Express, Daily Hate, and the Record. Although the Express and Mail may flip a coin and make up something about it being Daesh.

They need another status page so we can regularly check the status of the first status page, and while we're at it a second twitter account to tell us when the first twitter account will be updated.

JANET also connects schools and a lot of local authorities. The is the potential for some serious harm if social services lose connectivity but most organisation have a couple of fall backs at least for email.

Ummm...yes that's exactly what I meant. I was responding to the comment about most organisations have a backup email plan. We don't have a backup email plan because our mailboxes are hosted by MS.

Ahh got you - actually a large number of academic institutions these days use 365 with no backup email

Didn't notice this at all yesterday, but today the network is almost unusable (in Edinburgh). It's a very cunning attack, I can access the Reg, reddit, facebook, etc., but anything I need for actual work is completely unreachable. Oh well.

Re: Are you suggesting

As an engineering student revising for exams, no, I can't really claim El Reg to be essential to work. Maybe I could spin some of the articles and editorial into being relevant for my project management course, but that's mostly bullshit anyway.

Few schools I work with are all down. We have very limited internet, we can access this site and any HTTPS sites (so Google), but most of the net on port 80 is deaded.

service status

Our service status page is apparently externally hosted - so it's not available.

That was a good idea.

Changing my nameservers from the default university ones to use google's temporarily makes most sites accessible. though there are still a few which don't seem to be working.
