Connectivity issues, 98030

Is anyone aware of speed or connection issues affecting the 98030 ZIP code for 4-Mar-14 from about 07:00 to 22:15 local? (PST) I'd been going nuts troubleshooting a slow connect problem, which was affecting both incoming and outgoing traffic on our entire network. Then, interestingly enough, the problem mysteriously vanished about five minutes before I was going to call Comcast. Whattahey...??
