Bing Travel is back online at 11 a.m. Saturday, after 36–hrs of downtime following the fire and power outage at Seattle’s Fisher Plaza East data center facilities. “Bing Travel is a complex system of servers, databases and networking hardware that runs at massive scale,” explained Microsoft spokeswoman Whitney Burk via email. “It takes a bit of time after an interruption of power such as this one to bring it back online. Given power was restored at 2am today, we feel we had the service back up as quickly as was possible.”
