Expected Customer Impact: There will be a loss of DNS services on dns1.atlantech.net at 22.214.171.124 for a period expected to last up to 30 minutes.
<br /><br />
Reason for Maintenance: We are modifying traffic flow and firewall configurations in an effort to increase availability and resolve occasional DNS timeouts. DNS service to dns2.atlantech.net at 126.96.36.199 is not expected to be affected.
Master Ticket: 250543
Expected Customer Impact: This event will require a complete power disruption of up to 12 hours affecting all customer equipment in the Silver Spring data center, 1010 Wayne Avenue *only*.
Reason for Maintenance: Part 1: Rewiring of incoming electrical distribution feed and installation of a UPS isolation bypass; and Part 2: consolidation of two existing Uninterruptible Power Supply (UPS) units into a single new system. The key objectives of this project are:
* Improve the availability and reliability of power
* Increase the ability to isolate faulty electrical distribution equipment without disrupting normal datacenter operations
* Replace existing legacy power equipment with newer, more reliable and efficient equipment.
To accomplish these objectives, a complete power interruption is required. Furthermore, given the extensiveness of the work involved, this outage is expected to last up to twelve (12) hours. Once Part 1 of the maintenance is complete, the datacenter will operate on generator power for another twenty-four (24) to thirty-six (36) hours during Part 2 of the maintenance. This work will be performed during a weekend overnight to minimize operational impact. The datacenter power disconnect will occur at 10:00PM EDT on Friday, June 22, 2018, and will be restored about 10:00AM EDT on Saturday, June 23, 2018. There is a reasonable chance that the power disconnection will take less time than expected. There is a small chance that it will take longer.
As mentioned above, the datacenter will restore power and operate on generator power after Part 1 is complete. This will continue until Part 2 of the maintenance is complete which we expect to be during the evening of Sunday June 24th. The return to commercial power after Part 2 is complete will be transparent to the equipment in the datacenter.
We urge customers to prepare in advance for this event and Atlantech staff are available to answer questions and to provide assistance. For additional information, you may visit our Power Enhancement Project FAQ and subscribe to the page for further updates.
