Description Purodha Blissenbach 2006-12-19 10:51:44 UTC
Since almost 3 weeks, the list at [[Special:DoubleRedirects]] is not 
updated any more.

There are likely lots of double redirects in the Wikpedia, which we cannot 
resolve unless we accidentally find them.

Earlier, updates happened approximately twice a week. This was imho too 
infrequent, but at least bearable.


If - for some reason or another - the list of DoubleRedirects cannot be 
kept up do date, let us preferrably disable it, than showing outdated 
bogus entries only, resulting from programming errors.

Just for the records, in several wikies, several or all of the cached 
special pages were not updated since about end of Novembre or early 
Decembre. A common cause is likely, server admins are very likely 
aware of it. 

Maybe, there is a connection to the unavailability of replicated data 
on the toolserver (data could not be recovered after a power outage 
and is being restored - partially done already, and likely back to 
normal operability around christmass or earlier) *If so*, cached data 
is likely going to be refreshed at regular intervals before the end 
of the year again.

Query caches on Wikimedia sites don't depend on either of the toolservers. More
likely, the cron job we run to update them has been disabled deliberately, or
it's broken and no-one has noticed.
Comment 4 Rotem Liss 2006-12-21 15:59:23 UTC
Note that several wikis are updated daily.

Comment 6 Purodha Blissenbach 2006-12-21 23:07:49 UTC
For the ksh:WP, we'd be happy with daily updates for the time being, 
since we had a series of renames, and quite many bot changes to pages 
which may have resulted in many hundreds of duplicate redirects, and 
we run a bot solving them automatically, that relies on the cached 
data of the Special:DoubleRedirects page.
Comment 7 Purodha Blissenbach 2006-12-30 02:03:57 UTC
The problem may be solved. At least some chaches are fed 
with new data.

Seems good again :)
