Error
MediaWiki version: 1.36.0-wmf.10
message
Error fetching URL "http://localhost:6007/echoseen/v1/global%3Aecho%3Aseen%3Aalert%3Atime%3A59877388": (curl error: 28) Timeout was reached
Impact
Lots of short bursts of errors like the above in the mwdebug2001 logs, starting yesterday:
https://logstash.wikimedia.org/goto/8a0050058a844886a3e27727735f7b96
(Noticed while deploying something unrelated.)
All appear to be timeouts to various services via Envoy. Recent occurrences appear to be limited to mwdebug2001.
Notes
Nothing in /var/log/envoy/*.log which seems to correspond with the errors in logstash.
