Problem Report: Off Campus Connection Down

Posted by postprob on March 28, 2008 at 11:15 AM

Problem:   Off Campus Connection Down
Cause:     Failed firewall update
Affects:   All outbound internet connections to sites off campus
Started:   03/28/2008 11:00 AM
Resolved:  03/28/2008 01:00 PM

Notes:

the issue with the internet is resolved for major systems
(mail,web and the like) and should be resolved all other systems as well. we expect to still see some issues with access do to operating systems caching of various items. Please reboot if you are still having issues

Root cause is still being determined. Based on first hand reports this issue does not appear to be related to firewall rule changes. They were completed 8:30 am this morning. This issue surfaced around 11:00 am or so


A network engineer is looking into the problem and will update when they find the problem.

Problem likely due to problematic rule push to edge firewall early this morning. Primary firewall routing table was lost and redundant firewall configuration was lost. Primary routing table was rebuilt by engineers to correct problem. Network security engineer currently rebuilding redundant firewall and investigating reasons for failed update. ~ Ozanich
