but a lot of other sites and systems weren't -- even when accessing by IP. So it wasn't really a DNS issue. That's just an intermittent issue that Comcast customers deal with--I experienced that in Indiana a couple of months ago. I believe that it relates to them re-jiggering routers such that the appropriate default gateway for your modem changes, but because your modem is already up, it doesn't get notified of the change. So the modem doesn't send the message to the correct router, and the router it sends it to may or may not know how to get it to the destination.
