At 9:15am on Wednesday November 2nd, 2016, Weather Decision Technologies performed a systems upgrade on the GIS services stack. These upgrades allow for greater redundancy, product availability, and speed. The changes should be transparent to your operations, however stale DNS entries may exist, pointing you to the old system. Performing a DNS flush should point you to the new system.
As always, please contact firstname.lastname@example.org or call 1-866-429-5578 if you have any questions.
