We reported this morning that an outage had occurred causing our Data Center to go offline. We are pleased to report that the data center outage has been resolved, all systems are now back online, and our teams have resumed full operations.
Due to the approximately 18 hours that we were down, test results will be delayed. We anticipate being caught up and returning to normal turnaround times by the end of this week.
