Infrastructure is performing major Perl version upgrades (5.20->5.22), and requires some downtime to rebuild Perl modules on a few systems with heavy Perl usage.
Please check back on infra-status to see updates for exact scheduling of each affected service, but all services should be completed not later than 2017-02-28.
The updates to lists.gentoo.org are now complete.
Date range extended to 2017-02-28.
