Hey all, https://addons.thunderbird.net/ (ATN) is currently available in roughly the code state that it will go live. The database and file store are still on the old copy from late last year, but that will be updated this week after addons.mozilla.org turns TB/SM submissions off, and once we've verified that everything works, addons.mozilla.org will be redirected to addons.thunderbird.net(see: github issue <https://github.com/mozilla/addons-server/issues/6390>). *Note that anything you do on the site now will be overwritten by the database copy, so don't rush to update or upload add-ons*. I've uploaded an add-on that modifies Thunderbird's prefs to point at the new site, and it can be used for easily testing it in any current version of Thunderbird. You can find it here <https://addons.thunderbird.net/en-US/thunderbird/addon/thunderbird-addons-test/>. The add-on doesn't do anything other than modify prefs, and removing it will restore the prefs to defaults. Code is here <https://gist.github.com/Sancus/de9c386630b343f54d1231c402a07fdb> if anyone is curious. I've tested add-on installs from within Thunderbird, uploading a new add-on, and the review process. Because the database is old, hardly any add-ons are marked as compatible with TB60 on ATN, but if you are running a release version you should be able to install stuff, and you can search for and remove/install the Thunderbird Addons Test, which is marked compatible up to TB65. The site may go restart/briefly go down at any time until the AMO redirects are turned on(which will be announced), but there shouldn't be any extended(>15 minutes) downtime. If any major downtime is required, it will be announced here. There is also an email scheduled for July 10 to developers on AMO so this is not the only communication that will be going out. Issues can be filed at https://github.com/thundernest/addons-server/issues Known Issues: 1) https://addons.thunderbird.net/en-US/firefox/ and android are still available for now. Eventually they will redirect back to addons.mozilla.org, the redirects aren't live to make it easier to look at the firefox sections as the process to delete Firefox-only add-ons runs. 2) Currently emails are turned off, because the process to delete Firefox-only add-ons sends an email for each one deleted and that might overwhelm our mail provider. These are working and will be enabled later. 3) Add-on stats on number of users may not visibly update for the first week or two, but the data shouldn't be lost. More information on this to come.

Hey all, We are going to start the final database and file copy, so the site is going down. Not sure for how long, but it shouldn't be more than 24h. Hopefully much, much less.
