[announcement] IMPORTANT: Matrix chat server switchover: need to act || Scheduled Downtime

Dear GNU Radio community,

Monday, the 13. of September, at 12:30 UTC

we will temporarily shut down the Matrix homeserver. This means that if you have a
@username:gnuradio.org Matrix account, it will temporarily stop working.

We expect the Matrix infrastructure to be up and running, at better performance,

Monday, the 13. of September, at 19:00 UTC.

Everything will work as before. Any message sent to you (or a channel you're in) while
we're offline will simply arrive as soon as we're back.

***You will be logged out automatically.***
Right now is a good point in time to verify you know your password. You will have to log
in afterwards. This will also apply to mobile clients.

There is another thing, though: For private chats, Matrix enables end-to-end encryption by
default, so your messages are save and unreadable for anyone but you even if someone takes
over the homeserver. But that means:

***If you don't have a backup of your cryptographic secrets, you will NOT be able to read
your old private messages after the move*.**

For your private messaging to be readable after, you need to enable an encrypted key
backup before the migration.
It's easy: In short, if you're using chat.gnuradio.org, go to Settings -> Security &
privacy -> Secure Backup and click on the large "Set up" button, as shown in here:

If you have any questions feel free to either reach out to us at admin@gnuradio.org or
