(The Hosting News) – Monday was a highly unusual day for Google’s Gmail service. The popular email platform faced an unexpected outage – persisting for a brief period of time
Users reportedly received Server Error 502 messages and when they were able to access the platform, the service was extremely slow.
The reasoning had remained vague while some noted it also affected company’s Chrome web browser. However, Google recently outlined the root cause for the errors in a postmortem report.
At issue was a software bug contained via an update to Google’s load balancing capability, something the company was attempting to roll out during the time of the outage via its data centers.
“A bug in the software update caused it to incorrectly interpret a portion of Google data centers as being unavailable,” commented the company in its report.
Load balancing is used to reroute user requests to the data centers themselves.
The company, meanwhile, is undertaking an internal study that includes new measures such as altering the load balancer update and configuration processes.
While Gmail appeared the one service primarily impacted, other Google platforms including Google Drive, Chat, Calendar and play were affected as well.
