Impact
Some users are accessing a url (presumably linked or forwarded from somewhere), and are receiving a generic system error page that they will not understand.
The problem is marked as an application error and thus uses HTTP 500, which means it is not cached, and contributes to raise error levels for production.
Notes
Happens every other hour, not very frequent. A few example urls:
- enwiki HTTP GET /w/index.php?title=Special:ExternalGuidance&from=en&to=en&page=*******&targettitle=&service=translate.googleusercontent.com
- enwiki HTTP GET /w/index.php?title=Special:ExternalGuidance&from=en&to=en&page=*******&targettitle=&service=translate.googleusercontent.com
