Digital Realty has scheduled a major power maintenance for our chi02 data center (350 E Cermak Rd, Suite 240 West, Chicago). This power maintenance is not expected to be disruptive due to the improvements made during the work completed last fall. Date: Saturday, July 26th through Sunday, July 27th, 2014 Customer Impact: This maintenance will involve transferring all data center electrical load over to generator, then shutting down the UPS and utility power systems completely for de-energized maintenance. During the maintenance, the PDUs will be set to bypass all of the systems being shut down, and will remain online. They will be inspected using infrared technology to validate that they are operating properly. If any problems occur, maintenance will be stopped and all systems restored to normal operation. There is NO planned power interruption for any customers, however due to the temporary removal of redundancy, it is possible for a fault of the generator or a breaker could cause one or more PDUs to be interrupted. Using A+B power redundancy in your cabinet reduces the risk of an interruption due to a fault. Dedicated server and shared colocation customers in chi02 are already served by redundant A+B power. chi02 hosts the Chicago core network, so in the event of a catastrophic failure, it is possible that the network connectivity for Chicago could be interrupted. Facilities outside of Chicago should be unaffected. If you have any questions or concerns about this maintenance, please contact us via our helpdesk or by email. | |
