3. Turn up of new MPLS routing gear in WDC complete.
4. Migration of the private network in Dallas to the new network is complete.
5. Migration of the private network in Seattle to the new network is complete.
6. Migration of the private network in WDC to the new network is complete.
7. Migration of the internal management network in Dallas to the new network is complete.
8. Migration of the internal management network in Seattle to the new network is complete.
9. Migration of the internal management network in WDC to the new network is complete.


The migration of the public network has been postponed until Sunday, April 25th, 2010 due to time constraints. A new forum thread will be created about what is being done during that window.

Date: Saturday, April 24th, 2010 (04/24/2010)
Start time: 12:00 AM CDT
End time: 7:00 AM CDT
Duration: 7 hours
Service Affected: Public Network, Private Network
Reason: Network Migration
Location: All Datacenters

==================================================

Datacenter Engineers will be conducting maintenance on the transport gear that provides connectivity between data centers and to peering exchanges. During this maintenance window, traffic will be gracefully shifted to other providers. Engineers will be bringing new backbone routing equipment online in the following locations:

POPS:

LAX - Los Angeles, CA
SJC - San Jose, CA
DEN - Denver, CO
CHI - Chicago, IL
ATL - Atlanta, GA
NYC - New York City, NY
MIA - Miami, FL

Datacenters:

DAL - Dallas, TX
SEA - Seattle, WA
WDC - Washington, DC

In conjunction with bringing this equipment online, Engineers will be turning up new circuits linking these locations together. Transit and peering circuits within each location will also be turned in another maintenance window. During this, customer traffic destined for data centers DAL01, SEA01, and WDC01 will be rerouted either over the public Internet or through other paths for private network connectivity. Datacenter Engineers expect minimal impact to customers as traffic will be shifted prior to the event but some routing anomalies are expected during this process as routes re-converge.

Once completed and circuits verified, service will return to normal.

Again, Datacenter Engineers expect minimal impact to customer services once traffic has been shifted during this maintenance window.

The file system check completed and the system is back online

On Wednesday November 21st starting at 9am pst we will be taking the sjc003 server down to run a file system check on one of the partitions the operating system is reporting to have issues. This is necessary maintenance as otherwise the problem could result in an unplanned outage and potential data loss if it's a file system check is not done within a reasonable timeframe. We've set aside a window of 3 hours meaning the window ends at 12pm pst. We estimate the actual file system check will take about an hour and a half to be completed. We scheduled the window based on the usage patterns of this system where during this window it sees significantly less traffic than the rest of the day.

Date: 11/20/2012
Start time (PST): 9:00am
End time (PST): 12:00pm
Duration: 3 hours
Estimated Down Time: 120 minutes
