--- TIC-TECH message:
The Washington State K-20 Network has provided us with an explanation of
yesterday's Internet outage, for those who are interested.
The Washington State K-20 Network links together all Washington K-12 school
districts, community colleges, and 4-year colleges. It is the means by which
the Seattle Schools network connects to the Internet.
Yesterday morning, one of the colleges was having problems sending and
receiving information. In an effort to resolve the problem, K-20 Network
technicians made a configuration change to the router serving that college.
There was an error in the configuration that resulted in sending incorrect
information to all the other routers on the K-20 Network. The result was
that no one on the K-20 Network could reach the Internet until the
configuration error was fixed.
(For those interested in the technical explanation, K-20 placed static
routes in the college router and inadvertently allowed the router to
broadcast those static routes. Since static routes take precedence, all the
K-20 routers began using the routes that were intended only for this one
college.)
Thanks,
Judy
