TalkTalk customers who need to use a remote desktop tool are on the warpath after the UK ISP blocked TeamViewer for the second time this year, ostensibly in an attempt to protect users from potential scammers. A screenshot seen by The Register showed that had been blocked as part of TalkTalk's Scam Protect …

      - how ?

      - why ?"

      I'm pretty certain that Virgin media are throttling any encrypted traffic that goes through a VPN, because I get 1/10th of the rated speeds when using it.

      I've double and triple checked with my VPN provider and they have assured me that no traffic management was being applied to my traffic, they even informed me that at some of the times I've reported bad speeds I was on servers that showed less than 5% load. I also have proof (screenshots) that when I was using Sky Fibre, I was getting about 8/10th of my rated speed, and was in fact throttling my own speeds to avoid swamping my inbound connection.

      VM as usual are of no help, refuse to admit that they are doing this and have so far refused to compensate me for the degradation.

      Currently battling with them to severe my contract over it being a breach of contract so I can feck of somewhere decent instead.

      My experiences with VM have been shocking, from the bodged install where the engineer caused damage to my property, failed to fix and only paid for the damages after months of complaining... to the time when they charged my elderly mum £99 for using 800mb f extra data when their own app told her she needed to turn wifi off to authenticate... and then refused to refund her... End result is the loss of two mobile phone contracts (hers and mine) and as soon as I can get out of my landline/fibre contract I'm leaving... and all because of their nasty immoral and downright insidious business practices.

      VM can go f*ck themselves.

        Re: Begs the question(s) ...

        You have my sympathy.

        I have a Static IP through them, and the GRE tunnel they use to provide Static IPs offers the same “performance” feature.

        I pay for a 350/20 line and get 20/20 at best.

        From reading on the web you only get decent speeds if you get rid of Static IPs. I need a Static IP and they never mentioned how far below advertised speeds it would be...

        Re: Begs the question(s) ...

        They have been doing this for coming up to 5 years now. Basically they throttle everything except anything they have white listed. I used to be able to get round the throttling of P2P by encrypting the traffic, but when they changed to this method there was no way round it. I switched to slower 75Mb BT Infinity which effectively was faster as it is untouched (other BT packages are throttled). To get untouched traffic with VM they now have the option to pay for the gaming package I believe, it's the most expensive of course.

        The US is wondering what the lack of Net Neutrality leads to, well we already know as it is here in the UK. If you want to have proper Internet access untouched then you have to buy the top *fast* package, which really just means they haven't screwed with it..

        1. Alan Brown Silver badge

          Re: Begs the question(s) ...

          "The US is wondering what the lack of Net Neutrality leads to"

          This (and at least here in the UK you have the option of going to another provider)

          MADISON RIVER: In 2005, North Carolina ISP Madison River Communications blocked the voice-over-internet protocol (VOIP) service Vonage. Vonage filed a complaint with the FCC after receiving a slew of customer complaints. The FCC stepped in to sanction Madison River and prevent further blocking, but it lacks the authority to stop this kind of abuse today.

          COMCAST: In 2005, the nation’s largest ISP, Comcast, began secretly blocking peer-to-peer technologies that its customers were using over its network. Users of services like BitTorrent and Gnutella were unable to connect to these services. 2007 investigations from the Associated Press, the Electronic Frontier Foundation and others confirmed that Comcast was indeed blocking or slowing file-sharing applications without disclosing this fact to its customers.

          TELUS: In 2005, Canada’s second-largest telecommunications company, Telus, began blocking access to a server that hosted a website supporting a labor strike against the company. Researchers at Harvard and the University of Toronto found that this action resulted in Telus blocking an additional 766 unrelated sites.

          AT&T: From 2007–2009, AT&T forced Apple to block Skype and other competing VOIP phone services on the iPhone. The wireless provider wanted to prevent iPhone users from using any application that would allow them to make calls on such “over-the-top” voice services. The Google Voice app received similar treatment from carriers like AT&T when it came on the scene in 2009.

          WINDSTREAM: In 2010, Windstream Communications, a DSL provider with more than 1 million customers at the time, copped to hijacking user-search queries made using the Google toolbar within Firefox. Users who believed they had set the browser to the search engine of their choice were redirected to Windstream’s own search portal and results.

          MetroPCS: In 2011, MetroPCS, at the time one of the top-five U.S. wireless carriers, announced plans to block streaming video over its 4G network from all sources except YouTube. MetroPCS then threw its weight behind Verizon’s court challenge against the FCC’s 2010 open internet ruling, hoping that rejection of the agency’s authority would allow the company to continue its anti-consumer practices.

          PAXFIRE: In 2011, the Electronic Frontier Foundation found that several small ISPs were redirecting search queries via the vendor Paxfire. The ISPs identified in the initial Electronic Frontier Foundation report included Cavalier, Cogent, Frontier, Fuse, DirecPC, RCN and Wide Open West. Paxfire would intercept a person’s search request at Bing and Yahoo and redirect it to another page. By skipping over the search service’s results, the participating ISPs would collect referral fees for delivering users to select websites.

          AT&T, SPRINT and VERIZON: From 2011–2013, AT&T, Sprint and Verizon blocked Google Wallet, a mobile-payment system that competed with a similar service called Isis, which all three companies had a stake in developing.

          VERIZON: In 2012, the FCC caught Verizon Wireless blocking people from using tethering applications on their phones. Verizon had asked Google to remove 11 free tethering applications from the Android marketplace. These applications allowed users to circumvent Verizon’s $20 tethering fee and turn their smartphones into Wi-Fi hot spots. By blocking those applications, Verizon violated a Net Neutrality pledge it made to the FCC as a condition of the 2008 airwaves auction.

          AT&T: In 2012, AT&T announced that it would disable the FaceTime video-calling app on its customers’ iPhones unless they subscribed to a more expensive text-and-voice plan. AT&T had one goal in mind: separating customers from more of their money by blocking alternatives to AT&T’s own products.

          VERIZON: During oral arguments in Verizon v. FCC in 2013, judges asked whether the phone giant would favor some preferred services, content or sites over others if the court overruled the agency’s existing open internet rules. Verizon counsel Helgi Walker had this to say: “I’m authorized to state from my client today that but for these rules we would be exploring those types of arrangements.” Walker’s admission might have gone unnoticed had she not repeated it on at least five separate occasions during arguments.

      I would never admit to being a TT customer, but due to the fact that my exchange has just BT and TT available, the ISP that I pay money to is actually reselling me TT. So, a customer, though an indirect one.

        @Martin an gof

        That's probably because the phone coop (other ISPs who resell TalkTalk services are available, Andrews & Arnold for example) will be dealing with the TalkTalk Business (ie the old Opal & Tiscali Business part of TalkTalk) side of the business rather than TalkTalk Residential.

      I think they also do something horrible to VPNs, as she can't get onto the network of the charity she consults for from home. Their IT say it's a common problem with TalkTalk. Though their IT are a bit rubbish, so it could just be not wanting to help.

        Not just TalkTalk, Virgin, Sky and probably others.

        Basically, going back a bit, all of the above blocked the standard VPN ports on their home/residential broadband, because if you read the T&Cs the service was not intended for business usage - home working is business usage.

        I don't know about their current policies, but I do know that Demon (before they became Vodafone) didn't block traffic and EE's Home/residential broadband offerings are fully home office compatible.

        I think in the headline rush for speed (and TV), people have overlooked the detail:

        - Are VPNs supported

        - What is the traffic filtering and shaping policy

        - What does unlimited really mean

        - What is the contention ration

        - What is the down/up speed ratio

        - What are the SLA guaranteed down/up speeds

          Utter twaddle. Sky has not, and does not throttle VPN traffic. Or indeed any other traffic.

          1. The Dogs Meevonks

            Up until I left in April, I was on a 40Mb fibre package and could get on average 38Mb of those rated speeds, and throttled my incoming speeds through my VPN to 30Mb to avoid swamping my network and allow me to still do other things.

            They also gave me a 10Mb upload ratio, whilst Virgin give you a pathetic 5Mb... As soon as I can, I'm off... will be giving BT a try next if they offer me a decent price.

    Too Bad

    It's too bad that services and tools that allow remote access fail to provide a way for firewall and proxy administrators to limit the remote access feature. Desktop sharing alone isn't so terrible; it's the ability to allow unknown external actors to run roughshod over your binaries that has infosec bods putting a halt to the whole tool.

    It's a similar problem with network storage services like They lack a way to restrict uploads, even where downloads are not considered too much of a risk.

    1. tiggity Silver badge

      Re: Not related to NN, no matter how much you want it to be

      Because they are selling a service to customers, and what the customer wants should be important.

      They are selling internet access after all, not some curated walled garden, so not giving customers what they paid for if some sites are arbitrarily blocked.

      There may be valid legal reasons for blocking some sites (e.g. kiddie pr0n sites on official ban lists) , but no reason to block anything else.

      TeamViewer is legitimately (and quite widely) used by lots of people for work reasons (me included) - and blocking it is really not appropriate.

      If I want to block particular sites I will do it on my firewall thanks

      Re: Not related to NN, no matter how much you want it to be

      "Remind me again why an ISP shouldn't be allowed to control what goes through its network."

      Because people buy internet service.

      When the ISP is blocking services which compete with its internal offerings, then customers can go elsewhere. Except across vast tracts of the USA, where there is no "elsewhere" to buy from.

      The problem with breaching Net Neutrality is that everything is interconnected on a trust basis and if ISPs start restricting things, the whole model falls apart rapidly, leading to a Balkanisation of the Internet and severely eroding its utility.

    Being generous - it's Christmas - let's suppose for a moment that the TT management realise that they need to provide customers with a safe, reliable service, allowing for the fact that the bulk of their customers aren't going to be anywhere near the upper quartile of IT-savvy.

    Given their starting point of having had their customer data breached multiple times, how do they do that?

    1. Dan 55 Silver badge

      1. Disable common remote access protocols.

      2. Make enabling them require a call to TT. The chances of the scammer convincing them to hang up, call TT, get them enabled, hang up again, and wait for a new call are low.

      3. If they do manage then the calll centre will asks the customer why (because Windows Helpline told me to/because you just rang me and told me to), they can be told they're being scammed.

      Of course, if the outsourced call centre people are calling TT customers while at work then nothing would help.
