Scheduled Maintenance - Washington DC [07/12/2011-07/14/2011]

Date: Tuesday, July 12th, 2011 (07/12/2011), Wednesday July 13 (07/13/2011) and Thursday, July 14th (07/14/2011)

Start Time: 12:00 AM EDT

End Time: 08:00 AM EDT

Services affected: Public / Private Network

Location: WDC

Duration: 56 hours

Event summary:

During the maintenance, our provider will be replacing the existing CER and BBR routers (Cisco 7600 platform) with with new routers (Juniper MX platform) that will greatly enhance capacity and reliability in that market. Because of the scope of the changes that are planned they will be splitting the work across 3 nights beginning the morning of July 12th at 12:01am. This is necessary to ensure that the work can be done with the least impact to customers. This has been scheduled for:

Tuesday July 12th 12:00 - 08:00 AM EDT

Wednesday July 13th 12:00 - 08:00 AM EDT

Thursday July 14th 12:00 - 08:00 AM EDT

Customer impact:

In order to do this change with minimal impact to customers our provider will be replacing the routers one at a time. This will allow them to take down one of the redundant routers and unrack it, rack the new router and configure it, and insert it inline. Once they've completed insertion of the new router they will then repeat the process for the second router. Because these routers are deployed as a redundant pair they don't anticipate any measurable downtime. This work will likely result in some sub-optimal routing, connections will be disconnected as the routers are removed from service, and customers may experience higher than normal latency. There is also the potential for some connectivity issues during the work.

All work is expected to be finished by the completion of the Wednesday maintenance window. However, the window for Thursday was scheduled in the event engineers are unable to complete the work in time.
