Transatlantic Cable Fault Disrupts Internet In UK 394

Posted by timothy from the electrify-the-atlantic dept.
An anonymous reader submits "Web traffic between the U.S. and Europe has been hit after an undersea cable developed a major fault on Tuesday. Because the TAT-14 cable network is shaped like a ring, it should be able to cope with one such failure -- but unfortunately the consortium that owns it hadn't fixed an earlier problem, just off the U.S. coast. Just shows how systems with build-in redundancy can still go badly wrong...."

    It is redundant, unless we have 2 faults.

    We have a single fault...but we don't repair it.

    So then we have anouther one!

      My guess is that the initial problem may have been an undersea cable. Those generally take 2 or more weeks to fix, and if the weather is really bad, they have to pull the boats back in, delaying things further.

      No evidence, of course, but it seems like the most logical reason. Cables like the TAT-14 don't stay unfixed just because someone in management is lazy.

        You're new here, aren't you? Management is cheap, not lazy. Redundancy means that when something breaks they save money by not fixing it, not that they can keep running while they do fix it.

        They delays in repair may also be due to the bids they have out to fix it: A Greek sponge diver, the "Polynesian" pearl diver from an unnamed Florida amusement park and a crew from Bangalore with no diving experience or equipment, but a willingness to follow the diving script. There's also a chance that an unnamed "muff diver" may be employed as well, but executives are downplaying it as part of their don't ask, don't tell policy.

        Management originally wanted the crew from "Ghost Ship" because the chick was hot, but when they found out it was only a movie they had to look elsewhere.

      Remember that fixing faults in undersea cables isn't exactly an activity that you can do in 30 seconds. You've got to get a ship out to the location of the fault, hook the cable, and get it to the surface, and then fix it. There are going to be a limited number of cable ships [seafarers.org] which have the capability, and they might be busy elsewhere. Even once they start acting on the repair, they are going to take time to get to where the fault is (14 knots cruise speed isn't exactly the fastest ship around the QE2 cruises at 28 knots, and still takes a week to cross the atlantic. Remember a cable ship might be off in the other side of the pacific when it becomes free), and then time to get the cable and repair it. Therefore 'earlier this month' not being repaired is perfectly reasonable.

      The real problem is in the design of networks. Information networks are designed to be fault-tolerant (famously but erroneously attributed to a desire to withstand nuclear attacks) -- multiple connections and a "mesh" network mean that if nodes break, traffic is routed elsewhere and the network continues to function. This works great, and there's no problem with it. But the problem is, humans don't build networks this way, and economics is against doing so.

      If you're buying a network connection, you buy it from the best provider available, which naturally means network connections become concentrated to a few suppliers, who in turn find economies of scale and provide lower prices, thus attracting more customers. Thus the economics of building networks naturally produces networks that have a few or even single points of failure: we noticed this on September 11th, when the knockout of the huge links through New York noticeably slowed transatlantic traffic, even to sites other than CNN and the other news sites that were being toasted by demand at that point. Centralisation is something that we naturally do because it's economically efficient, but centralisation leads to problems for networks.

      In the energy sector, things are even less flexible, because energy connections are a lot more expensive to set up and difficult to maintain than information links. The US powercut was caused by the cascading failure of a daisy-chain of power stations around the great lakes. Nobody would build an information network that way any more, but it's still the natural way to build a power network. Italy's powercut was caused by a huge reliance on foreign power, supplied by JUST TWO LINKS to France -- one fell over, instantly overloading the second and knocking it out too.

      Yes, we are critically reliant on these fragile networks. And yes, economic realities tend to cause these problems, but not because of privatization: it's simply because humans naturally tend to build poor networks, because those are cheaper -- no matter who pays the bills. To solve the problem, we need to pay more attention to networking theory when building all of our networks, and provide regulatory incentives to build better networks of both kinds.

      Or one day, a critical failure will cause a cascading catastrophe, and it will be nobody's fault. We built the network to fail that way.

Recent ones are apparently treated to prevent sharks from chewing on them, which was an old problem. Fixing them involves sending out a big ship that hauls up cable from the ocean floor (they have a lot of slack so that this is possible), hanging the cable across the deck, fixing it, and lowering it back into the water.

    non TAT14 capacity (10G) and one oc48 direct to Copenhagen (that is ok).

    We (Opentransit) are currently not experiencing any congestion but are implementing a new 10G circuit to secure our topology until TAT14 is back to life (one leg at least).

    This transatlantic cable system is in full service, connecting the United States to the United Kingdom, France, The Netherlands, Germany, and Denmark.

    The cable system is a dual, bi-directional ring configuration using DWDM multiplexing with 16 wavelengths of STM-64 per fiber pair. The system also utilizes reverse direction protection switching in the event of failure of the service fiber.

    It has a dual route, transatlantic capacity of 640 Gbits on 2 service fiber pairs backed up by 2 protection fiber pairs. This configuration provides a capability of transporting 4,096 STM-1's or approximately 9,700,000 circuits across the ocean.

When a cut or fault occurs, the location of the fault is determined with a TDR or O-TDR [atis.org], the same way it works with a land based cable. They know the cable length to the fault and have a survey map of where the cable was layed. It is physicaly located with side-scanning sonar and robotic submersibles, then hooked and brought on deck for repair (each end in case of a break). Once repairs are complete, the cable is unceremoniously shoved over the side, or re-ploughed depending on the location and mission of the cable.

    Other carriers have working circuits on TAT-14 and another link (e.g. Apollo, Tyco, AC-1, Gemini) and may have some degraded service (depending on whether their transatlantic links are less than twice the size of their peak demand). FranceTelecom OpenTransit is an example of one of them.

    Interestingly, not many EU ISPs use TAT-14 North route, since it has a propagation delay of around 110ms (which is 40ms or so more than TAT-14 South from the UK and more than most other transatlantic cables)

    Most ISPs in Europe that I can see are fine. Certainly the big international transit ISPs (Sprint, L3, C&W, MCI et al) aren't showing any more trouble than normal.

    Whose fault were these faults? Were these faults the fault of the oceanic faults? I've heard some people say that these faults were the fault of faulty maintenance, but it seems to me that you can't fault them for the faults. Now perhaps that's a faulty assertion, but I really believe that the fault of the faults lies squarely upon the techtonic faults and not the fault of this supposedly faulty maintainers. I really doubt that the faults are their fault.

    I'm sorry.

    ...this post was all my fault. :-(

    As TAT-14 is a dual, bi-directional ring of cable, a single serious fault should not be enough to break it, as traffic would still be able to flow between the countries on the ring. Unfortunately, a part of the cable near the US coast had already suffered a technical fault earlier this month, which meant there was no built-in redundancy to cope with Tuesday's failure.

    I can hear it now:

    "Hey boss, half of the cable just failed. We need to get on this right away".

    The cable's still working, right?

    "Yeah, but if something else goes wrong, we're screwed".

    Look, that cable hasn't failed in ten years; let's put off repairing it until January. That way it won't affect our 2003 budget.

    But these things generally happen in pairs, and with no back up - well, we're taking an awful risk. If something else fails, most of Europe - well, I don't have to tell you the consequences. Plus, remember..the weather in January -

    cuts him off-- Not gonna happen! Put it on the schedule for mid January!

    Hopefully that manager is no longer employed....but don't be surprised if he winds up at Clear Channel! He sounds like just their kind of guy!

    As far as I'm aware the problem wasn't just limited to the UK but to the whole of Europe. One of our transit connection to the US using this Fiber, was disrupted. Following message we received from our transit provider:

    We are currently experiencing a catastrophic failure on the fiber ring that is
    affectively isolating Europe. We are researching the possibility of
    alternative connectivity, and will update you as we get more information.

    One more problem which was caused by this link outage is that our dns-servers (and those of multiple providers) where hit with a lot of dns lookups for lockdown.zonelabs.com (seems zonelabs firewall, queries that name). As the dns-server for that zone wasn't reachable anymore (no more traffic to the abovenet network in the US) the dns-servers had to do a query for each new lookup which caused a huge load. And effectively killing the customer dns servers, impacting traffic even more.

    I've found the whole notion of undersea cables fascinating ever since I read Neal Stephenson's Mother Earth Motherboard [wired.com]

    Reminds me of how we went through all this trouble at [UNNAMED CORPORATION] of making sure to mirror the root disks for all 3000+ servers, but nobody setup alerts or notifications of a disk failure. So even though all the disks were mirrored if one drive failed, nobody knew. So we ended up running most our boxes off one drive until the other drive went out. So sure, mirroring delayed a major problem, but the major problem still existed.

    We also had a similar problem with Fiber Storage. For all the servers they had run two seporate fiber runs to each box that needed to use the "SAN". Each server would have two fiber cards installed. This way if one network went out, it would just fall back to the other card. Well, of course, both cables were plugged into the same switch.. Smart. Yes, we did have a fiber switch go out once.

    ...customers may currently be experiencing problems with all Internet access, including Web browsing, email, ftp and newsgroups.

    So....there was just one ring to screw them all?
