A router fault at Sirv's primary datacenter caused inaccessibility of the primary cluster at 1251hrs UTC, causing Sirv to switch to its failover cluster. Normal service continued for all Enterprise accounts. Business and Free accounts returned an HTTP 503 status for the period.
All services returned to normal after 49 minutes at 13:40UTC, once the router fault had been resolved in the primary datacenter. This was a rare issue from our usually reliable datacenter. If you need 100% availability backed by an SLA, talk with us about our failover service that is part of our Enterprise plans.
