The enwiki<br>
database replica has been corrupt since about 30 April; I posted a bug<br>
report[1] on 2 May, but it hasn't even been triaged yet. In the meantime,<br>
there seems to have been further corruption within the past 24-36 hours,<br>
as evidenced by tools that report link counts (based on the replica) that<br>
are highly inaccurate when checked on the live wiki.<br>
<br>
I'm surprised this isn't causing problems for other users' tools (or at<br>
least that no one has complained about it). At a minimum, I know that the<br>
pagelinks table in the replica contains entries that don't exist on the<br>
live wiki. I would assume it likely is also missing some entries that do<br>
exist on the live wiki, although this is much harder to confirm. Other<br>
tables may be inaccurate, as well.<br>
