I wasn't here for a few days, but it's been slowing down intermittently today here as well. I have cable internet through PenTeleData, I usually never have problems with them, other sites are working fine.
I've noticed lots of sites getting slower & slower this past year. My DSL connection used to be just as quick as my buddy's cable connection. Now he's stayed the same while my Verizon DSL is like dial up at double the cost.
