Server Scheduled Maintenance
Posted by Mohammed Obeidat on 19 March 2014 02:51 PM

Data Centers’ Network Engineers, working in tandem with the hardware vendor, have identified an issue on customer routers which provides connectivity for your server(s) and back-end services. To prevent an unplanned outage resulting in significant downtime, Engineers will be performing firmware upgrades during a scheduled maintenance window.

Change Details:

Date: Wednesday, March 19, 2014 (19/03/2014)
Start Time: 07:00 PM UTC
End Time: 08:00 PM UTC

Duration: 1 hours

Services affected: Server connectivity and back-end services

During this maintenance, most of servers will initially experience a disruption in back-end services on the private network, such as DNS resolution, iSCSI, NAS, data backup, and SSL/PPTP/IPSec managed VPN access to servers (master back-end router) is rebooted for upgrade.

In addition to the router maintenance, SAN-based CCI and VPX instances will be shutdown/paused in order to maintain data integrity due the fact that they rely on storage subsystems that reside on the backend network. Once the routers have returned to service, all CCIs will be booted up and brought back online.

While the maintenance window is set for 1 hours from 19-March-2014 07:00 PM - 08:00 PM UTC, we expect the initial services and first Pod disruption to last less than 30 minutes , and disruption to each subsequent pod to last less than 30 minutes , as well. We expect a disruption of up to 30 minutes for some SAN-based CCI and VPX instances.
