As the PR guys have noticed, things have not been so rosey in the DC datacenter recently. There have been a lot of upgrades happening and equipment being shifted around to improve network performance. There is a rather LARGE upgrade coming up that should change things considerably.
In a continuing effort to improve the SoftLayer network, SoftLayer Engineers will be performing maintenance in the Washington, DC (WDC) facility the week of July 11, 2011. During the maintenance we will be replacing the existing CER and BBR routers (Cisco 7600 platform) with with new routers (Juniper MX platform) that will greatly enhance our capacity and reliability in that market. Because of the scope of the changes that are planned we 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 our customers. The details of the work are as follows:
Tuesday July 12, 2011 :: 12:00 AM - 8:00 AM EDT
SoftLayer Engineers will replace the CER01/02 distribution routers. In order to do this change with minimal impact to our customers we will be replacing the routers one at a time. This will allow us to take down one of the redundant routers and unrack it, rack the new router and configure it, and insert it inline. Once we've completed insertion of the new router we will then repeat the process for the second router. Because these routers are deployed as a redundant pair we 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. We will have engineers working on site to replace the equipment as well as engineers working remotely to mitigate any potential issues that arise as quickly as possible. It is anticipated that this !
work will consume all 8 hours of the scheduled window.
Wednesday July 13, 2011 :: 12:00 AM - 8:00 AM EDT
SoftLayer Engineers will replace the BBR01/02 backbone routers. As with the CER's we will be replacing these routers 1 at a time to minimize the impact to our customers. Also as with the CER's we anticipate that customers will experience some sub-optimal routing, connection disconnects as the routers are brought offline, and higher than normal latency, but we do not anticipate a complete service outage. This work is expected to consume all 8 hours of the window as well.
Thursday July 14, 2011 :: 12:00 AM - 8:00 AM EDT
While we anticipate being able to complete all of the work on Tuesday and Wednesday, we may need to extend some of the work into a third maintenance window. If this is necessary we will update the maintenance tickets with the pertinent information. If not we will cancel the maintenance for this night.
