So given the Matrix outage, I went and made an XMPP account.
People like to talk down flagship servers in the federated ecosystem, but honestly hunting down an xmpp server as a host with was a pretty needless exercise. I went with xmpp.is. Are they any good? No idea!
It didn't help that out of the pro-XMPP posts boosted into my TL, not one of them recommended a particular instance to set up an account. Without recommendations, I default to wanting something authoritative.
