There's a reason I've been recommending folks reliant on #Signal to familiarise themselves with #jabber (or #xmpp if you like).
Signal relies on one of the companies they aim to protect us from: amazon. If amazon goes down, so to does Signal.
Is that bad? Yes. Yes it is. It is very bad. You just had the faintest hint of a whiff of what that means today.
Jabber, on the other hand, is a #SelfHostable decentralised service that has been in continuous use and development since the 90s.
With my jabber server ( #Prosody) and my #android client ( #Conversations), my friends and family and I do everything we can do on Signal - text, quote reply, search, send media and files, voice and video chat... and it's all #e2ee end-to-end-encrypted, running on hardware and software we have total control over.
Go explore the world of options with Jabber!
