UPM / PGH System Downtime

Who/Where: 
UPM System including PGH
When: 
Sunday, May 12, 2013 - 00:00 to Monday, May 13, 2013 - 10:45
Why: 
UPM Router Malfunction
Account: 

* I found out that the main router lost some of it's configuration including BGP, good thing I have a back-up of the recent stable conf. and successfully restored it to Xun.
* Connection has been restored around 10:15 AM.
* Occurence of the problem might be related to the recent power failure.
