Change Details

From approximately 7:31 to 8:16 UTC, there has been instability on serving Wiki uncached content (mostly impacted would be authenticated users and bot, and POST requests), affecting at first commonswiki, but later most other wikis, albeit in a lower capacity. The impact between those timestamp was increased latencies (up to 5+ seconds to return results) and high level of errors (approximately 1/4th of request lost). This was due to overload on commonswiki requests blocking resources on most api & database servers, which in turn created contention on most other wikis. The issues were narrowed as triggered by SchlurcherBot at commonswiki, which was blocked from editing and sending requests to Wikimedia sites at 7:49 and 8:08, respectively.
