I might be overcautious, but seeing that content of static-bugzilla [[ https://encrypted.google.com/search?q=site:static-bugzilla.wikimedia.org | gets indexed by search engines ]], the current top banner on subpages (e.g. [[ https://static-bugzilla.wikimedia.org/bug52242.html | here ]]) might be confusing and contradictive (as you cannot log in anymore, you cannot access your votes or saved searches) for somebody directly ending up on a subpage of static-bugzilla who has not seen the frontpage.
**Only if** it's not a PITA to mass-change a line in each HTML file (if it is, please decline):
The banner on each page currently says
> Wikimedia has <a href="https://www.mediawiki.org/wiki/Phabricator/versus_Bugzilla">migrated from Bugzilla to Phabricator</a>. Bug reports should be created and updated in <a href="https://phabricator.wikimedia.org">Wikimedia Phabricator</a> instead. Please <a href="https://www.mediawiki.org/wiki/Phabricator/Help#Creating_your_account">create an account in Phabricator and add your Bugzilla email address</a> to it.<br>Wikimedia Bugzilla is read-only. If you try to edit or create any bug report in Bugzilla you will be shown an intentional error message.<br>In order to access the Phabricator task corresponding to a Bugzilla report, just remove "static-" from its URL.<br>You could still run searches in Bugzilla or access your <a href="https://old-bugzilla.wikimedia.org/page.cgi?id=voting%2Fuser.html">list of votes</a> but bug reports will obviously not be up-to-date in Bugzilla.
and could instead say
> Wikimedia <a href="https://www.mediawiki.org/wiki/Phabricator/versus_Bugzilla">migrated from Bugzilla to Phabricator</a>. Bug reports are handled in <a href="https://www.mediawiki.org/wiki/Phabricator/Help">Wikimedia Phabricator</a>.<br>This static website is read-only and for historical purposes. It is not possible to log in and except for displaying bug reports and their history, links might be broken. See the <a href="https://www.mediawiki.org/wiki/Phabricator/Help#Finding_the_Maniphest_task_corresponding_to_a_Bugzilla_bug_number">corresponding Phabricator task</a> for complete and up-to-date bug report information.
