I chatted a bit with tatsuhiko yesterday (since he arrived at San Francisco) about comcast being so-so (We agreed on that, though he seemed to have more problems than I did)
Well they did it again !
I don't know why but everything is now incredibly laggy, I have a lot of packet loss.
Last time, I was happy with their customer support at least, but I don't think the support will be able to do anything for temporary network sluggishness.
