Summary: Revision error on en.wikipedia.org, Internal error:
Unknown cluster "cluster16"
Product: Wikimedia
Version: unspecified
Platform: PC
OS/Version: Linux
Status: NEW
Severity: normal
Priority: Normal
Component: General/Unknown
AssignedTo: wikibugs-l@lists.wikimedia.org
ReportedBy: aaron.halfa...@gmail.com
I've discovered a single revision_id that, when requested from
en.wikipedia.org, causes an error that causes an "Internal Error" and crashes
an API query. When making an API query, the problem only happens when I try to
request the content. The error is out of the ordinary and that is why I am
reporting.
Revision id: 186704908
Problem observed for: 3 days
