The seven days of punishment for the being an alleged heavy user passed on Friday. The service was unchanged Friday and Saturday but has improved slightly today, Sunday. I can now get dial up speeds on the problem ports.
I found the speedtester at
http://myspeed.visualware.com/vr/index.htmlbest for such a slow connection. Ping is 60 ms and port 80 speed 1.1Mb
When my new ISP takes over on Monday I'll Post a comparison.
