In 2005–2006 a sysadmin blocked 79 IP addresses on all wikis as being
automatically-detected open proxies, without recording them in the block
log or attributing the block to any user account. These incomplete records
are now causing errors when MediaWiki tries to access them in various
places, see
https://phabricator.wikimedia.org/T189840.
Since these are all over 12 years old, it seems reasonably likely that many
of these are no longer open proxies. Rather than trying to fix the
incomplete records, I'm just going to remove them.
Any existing blocks of these IPs that are not causing errors will not be
removed. At first glance this seems relevant mainly to enwiki, where only 5
of the IPs have incomplete records. 21 are currently blocked there with
complete records (19 since 2005 or earlier), and the other 53 are not
currently blocked there.
The list of IPs is at
https://phabricator.wikimedia.org/P6876 in case
anyone wants to review them for potential reblocking.
