MATRIX.NET INTERNET EVENT ADVISORY WEEKLY SUMMARY
FOR 12 OCTOBER 2001

This is a summary of Internet Events that have affected Internet
performance during the week of 5 October to 12 October.

For more information about this summary and to see corresponding
graphs, please visit the Matrix.Net Web site at
<a href="http://www.matrix.net/ea/advisories/">http://www.matrix.net/ea/advisories/>.

----------------------------------------------------------------
11 October 2001

The JANET network in London and the colt.net network in Germany
experienced sudden performance degradation to sites in China. Both
networks share nodes that handle traffic to China through New York
City (alter.net). This event lasted approximately an hour. Users of
this path experienced an average .2 seconds increase in latency.

8 October 2001

The military operations in the Middle East have prompted Internet
performance changes across many West Asian states.

The rates of throughput in many of the states around Afghanistan now
show variable fluctuation during any 24 hour period. At the beginning
of military operations, Kazakhstan experienced drops in latency, as
alternate bandwidth became available.

Many Saudi Arabian hosts have become unreachable; gateways allow
traffic, but beyond the gateways, low-priority traffic disappears.

Pakistani hosts have experienced high levels of packet loss and
variability in latency. While transmissions have increased, no
significant bandwidth appears to have been added to accommodate the
traffic changes.

Kyrgyzstan and Kazakhstan both are experiencing performance declines,
but this may be due in part to the high traffic through the gateway
to Russia that many of the republics share. Latency times from
Kyrgyzstan to Russia and Kazakhstan to Russia leap from the 100ms
range on the Russian side to over 1000+ ms range at the republics.
