Internet traffic last night from around 18:45 to midnight was at unprecedented levels, not only hitting out commit levels for BT 20CN and 21CN but with the unlimited Be connections pushing the total to the gigabit capacity of some of our links. So, not quite melt but none the less a hell of a lot of traffic.
Our upgrade plans are well underway, and we hope to be ready to handle more than a gigabit by Christmas. We did not expect to need anything like that until the Olympics next year so the traffic levels last night were a bit of a shock!
Having been using IOS5 for many months, I can say I quite like it compared to IOS4, with a lot of small improvements and features, especially iMessage.
This is a graph of one of the Internet exchanges we use (LONAP), last night. It is nice to see how well they coped with such a burst in traffic.
