Users will experience a brief service interruption due to the switchover of our DNS configuration, and it may take a bit of time for DNS updates to be fully propagated to users' ISPs. Users may want to run the ipconfig /flushdns in a Windows command prompt following the switchover. This will mainly affect the old domains but the new ones may also be affected. Phabricator will be read only throughout.
The old domains will redirect to the new ones completely after this window.
As of now, mirahezebots.org domains are officially canonical.
