Last week, twitter is in the spotlight again, this time as the victim of a distributed denial-of-service (DDOS) attack. You may not have noticed, but Facebook fell victim to the same attack.

The attack took down Twitter’s network for almost three hours, while Facebook’s just got a little slower. It’s an example of something little-discussed by the media; Facebook’s network is a rock. We don’t know which companies bore the brunt of the denial-of-service attack, but Twitter, Facebook and Google ( GOOG – news – people ) are working together to investigate it.
This year, Twitter has improved response time and done a lot to banish the cute whales and birds that famously explain away down time. But Thursday’s DDOS attack shows how the networks function in extreme conditions.
“We’re continuing to monitor the situation to ensure that users have the fast and reliable experience they’ve come to expect from Facebook,” says Facebook spokesman Barry Schnitt. Translation: We don’t do downtime.
