The BBC was at the forefront of service outages this week, suffering downtime across the weekend on its iPlayer and website and continuing to glitch into the week, depriving Brits of their dose of Auntie-made telly. Despite the many tweets that flooded its Twitter account, the corporation chose to resolutely stick with the whole “we’re working hard to resolve” line, without any further details. Folks were not happy:It took until Thursday for the state broadcaster to let folks in on what happened, in a lengthy tech-heavy blog post from digital distie controller Richard Cooper that still failed to say exactly what kicked off the problem. After a description of the servers the Beeb runs and how it has two data centres running simultaneously to back each other up, Cooper basically admitted that the service got overloaded, but how that happened didn’t feature in the post:At 9.30 on Saturday morning (19th July 2014) the load on the database went through the roof, meaning that many requests for metadata to the application servers started to fail.The immediate impact of this depended on how each product uses that data. In many cases the metadata is cached at the product level, and can continue to serve content while attempting to revalidate. In some cases (mostly older applications), the metadata is used directly, and so those products started to fail.

Apparently at the same time as the database hit the rocks, the BBC homepage and iPlayer both ran into trouble as well:At almost the same time we had a second problem. We use a caching layer in front of most of the products on BBC Online, and one of the pools failed. The products managed by that pool include BBC iPlayer and the BBC homepage, and the failure made all of those products inaccessible. That opened up a major incident at the same time on a second front.So good on the problem descriptions, but how exactly did the Beeb end up with tech failure on two fronts? Auntie can’t, or won’t, say:We will now be completing the forensics to make sure that we’ve fully understood the root causes, and put in place the measures necessary to minimise the chances of such interruptions in the future.And finally, the Yorkshire police appear to have mistaken the open Wi-Fi hotspot network BT Fon for private home wireless connections and issued a warning to householders to tighten their security. A Reg reader from Heckmondwike claims that local cops wrote to residents about the issue after he had a run-in with a neighbour:One particular local householder (who is known for obnoxiously flaunting the cross of St George) threw a fit after catching me reading The Register on my tablet, using a BT Fon hotspot. After a rant about stealing internet access, he must have phoned the police because our local plod then sent letters to all the householders advising them that someone is stealing internet access, so they should change their passwords.
