Maintenance Window: Saturday May 14th 2011, 12:01am - 3:30am Eastern Time
Affected Device: dist02.tor1
Affected Customers: physically connected customers
Service Impacting: Yes - connected customers can expect to see short periods of latency and packet loss during this maintenance window.


Details: As per the postmortem regarding the 04-May-2011, and 06-May-2011 network incidents, we will be using this maintenance window to implement policers, and QoS features to help protect the networks distribution layer in the event of future attacks. Priority Colo staff will also be onsite, replacing the fans in each distribution router with new high speed fan trays in preparation for the new supervisor cards.

Just an update this notice:

The maintenance notice originally sent to customers on Monday said "EST" for the time zone. A customer helpfully reminded me today that we're in EDT timezone technically. This maintenance (and any time we say Eastern Standard Time in general) should refer to the local timezone, including daylight savings time as applicable.

I hope this doesn't create any confusion.
