Thanks. I was myself suspecting that Internet -- Internet 2 issues
might be at the root of the problem. Your response helps me identify
that switchover point.
With enough datapoints and responses it is easier for me to provide a
concise report to my ISP tech support, otherwise they just say the
problem is with my browser... In other words, if I speaka da geeka in
sufficient detail, the frontline support staff get clueless enough to
refer me to the people who actually know enough technical stuff to
get things done, usually within the hour.
The last time that happened, and I couldn't contact a selection of
sites in the US for a couple of days, I sent a tracert that showed
how a couple of the ISP's own routers had somehow started playing
pingpong with requests (...>A>B>C>B>C>B>C... loop ad infinitum).
