Date: 01-11-2013
Start time: 10:18
Services Affected: SJC01 – Public Network
Device: fcr01a.sjc01
Location: sjc01
Duration: Emerging Issue
Description: Beginning at 11-Jan-2013 03:18 UTC, we have detected a high CPU condition on the front-end customer router fcr01.sjc01. While it is continuing to forward customer traffic normally, some servers behind this router with short or expiring ARP caches may intermittently be experiencing troubles with Internet accessibility. Network engineers are investigating to determine how to correct the condition while minimizing risk of further customer impact, however additional disruptions may occur as work is performed to stabilize the network.

As of 11-Jan-2013 05:00 UTC Network Engineers have not yet been able to locate the source of the high CPU via non-intrusive data gathering begun to shut down parts of the SJC01 network, and must begin intrusive work of shutting down parts of the network in order to locate the source. This will cause extended disruptions for front-end Internet facing traffic for servers in SJC01 while the investigation and remedial work continue.

As of 11-Jan-2013 06:00 UTC Network Engineers have performed a reboot of router fcr01.sjc01 in order to clear out any errant condition which may have occurred as a result of CPU exhaustion for an extended period of time, and are working to turn up server connectivity one row at-a-time.


Demikian kami sampaikan, terima kasih atas perhatian dan kerjasamanya.
