<p><strong><a href="http://groups.google.com/group/google-appengine/msg/ba95ded980c8c179">App Engine outage postmortem</a></strong></p> Interesting peek behind the scenes. The primary cause of the error was a bug in a GFS (Google File System) Master server caused by a MapReduce process sending a malformed filehandle, reminiscent of the error which took down S3 last year. <p>Tags: <a href="https://simonwillison.net/tags/downtime">downtime</a>, <a href="https://simonwillison.net/tags/gfs">gfs</a>, <a href="https://simonwillison.net/tags/google">google</a>, <a href="https://simonwillison.net/tags/google-app-engine">google-app-engine</a>, <a href="https://simonwillison.net/tags/s3">s3</a>, <a href="https://simonwillison.net/tags/postmortem">postmortem</a></p>
