Incident Report re: Service Outage 25th November 12:52-13:05 and 15:32-17:12 GMT
What Happened
Yesterday we suffered two incidents, one starting at 12:52 GMT lasting for 13 minutes resulting in very slow response times and another one starting at 15:32 GMT lasting for 1hr 40 minutes, which included some periods of full loss of service.
Service was restored to normal at 17:12 GMT and all sites were up and running with normal response times.
Why It Happened
We suspect the initial causes of the incident may have been a user uploaded file (or files) that resulted in a denial of service condition by causing our image conversion software use up excessive resources while processing the file. It may have been uploaded multiple times and this repeated action exacerbated the problem. Our image processing software has processed millions of files in the past without such issues. We are taking immediate steps to identify the cause and have already released a patch which we feel should prevent this happening again.
