AT&T having network problems

I was puzzled and annoyed for most of the day with slow internet response times. I rebooted my workstation and server but I am pretty sure it was outside of my control. It finally cleared up this evening while I was cooking dinner. It bothered me because my intranet access was affected. My intranet uses several webparts that access the Internet so I guess my web page had to wait for each of those webparts to time out. I need to re-evaluate my design.
