Description

Error

MediaWiki version: 1.35.0-wmf.36

message

PHP Warning: socket_sendto(): Host lookup failed [-10002]: Host name lookup failure

Impact

API usage logs and error telemetry sometimes missing due to dns/socket failure

Notes

Noticed around a thousand of these earlier today, ca. 13:05 with a smaller cluster a bit later. Brief network failure?
