The other day the entire BBC network of site went down, setting off an avalanche tweets on the social networking site Twitter, with theories of a distributed denial of service (DDoS) attack and complaints of how this could even happen in the first place.
Steve Herrmann, editor of the BBC news website “Normally this would not cause any problems as we plan for events like this and run backup equipment. However, in an unusual turn of events, these also failed, meaning that the whole of BBC Online became unavailable. A number of internal services were also affected.”
But according to the BBC’s controller of digital distribution, Richard Cooper, “For the more technically minded, this was a failure in the systems that perform two functions.” In addition, he explains how this works, “The first is the aggregation of network traffic from the BBC’s hosting centres to the internet. The second is the announcement of ‘routes’ onto the internet that allows BBC Online to be ‘found’,”
However, following all of the theories and explanations, it seems that the real reason for the down time, was router failure after all, you would think that they would have back systems, well they do and guess what? Yes, they failed too!
