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!
