Unplanned Outage: Problems accessing certain FUSD sites: resolved at 10:30am
This morning, until 10:30am, certain users were not able to reach the following sites from inside the FUSD network:
rea.fresno.k12.ca.us
mail.fresnounified.org
*.powerschool.fresnounified.org
Users outside the FUSD network were able to reach these sites, and users inside the FUSD network were able to reach other Internet sites not belonging to FUSD.
Users affected: Anyone using statically assigned DNS server settings of 172.16.1.10. Those who have DHCP assigned DNS server addresses of 10.223.231.12 or 172.16.5.68 would have been able to reach all of the sites except for fresno.k12.ca.us addresses during the outage period.
The cause of the problem was a routing error on the Firewall Services Module. This error was introduced late Friday evening when we did work on the firewall. We did not become aware of the problem at that time, because we don't use the 172.16.1.10 DNS server and did not experience any of the problems accessing the above sites.
