After i post about my complaints on this blog, i went to bed and when i woke up this morning, the speed i gained this morning is the normal speed i usually get. It seems that they have located the problem and get it fixed. But, it's weekend and not many people go to office, so probably it was one of the reason it is faster. Also this is early in the morning, so the current speed can't be used for determining whether they have fixed the problem or not.
We should see for another few days, mostly on Monday where all people are starting to get into the office again and start consuming bandwidth
Another good news is that W3C's Annotea Server is now back online after Ralph rebooted the machine. Thanks to Marja, Eric, and Ralph for their support for my thesis.
