Subject: Asia connectivity outages, from the field

Dave,

[For IP, if of interest.]

I've been in southern China (Changsha, in Hunan province) since
Sunday (local time).  My observations have been that network
connectivity is significantly worse than usual, but is also
(unsurprisingly) somewhat time-of-day dependent. I have fairly good
success in the early morning; on the other hand, during evening hours
(local) it's difficult to connect with servers in the States. There
are also, of course, dependence on the particular services needed;
some Internet sites appear to be either better connected or have
services partly provided out of China, enhancing availability (Google
is a notable example of good perceived connectivity).  I also suspect
that the phenomenon includes increased network congestion due to a
much larger number of retries after failed attempts (to which I find
myself contributing, for example hitting the refresh button in hopes
of a better result).

We're hearing that services are up to the "70%" level (could be true,
could be PR) but that repairs have been delayed by a problem with a
repair ship and rough weather at sea.

Cheers,

Philip Lehman
