From this post (https://sopuli.xyz/post/15865566) on !AskMbin@fedia.io
It’s very likely related, but we also figured out that both of debounced’s (the admin of kbin.run) accounts on GitHub and Matrix were deleted last night. So there is a possibility that kbin.run is no more.
Ah, okay. I looked at their profile, but it didn’t list a Matrix username (or at least, that didn’t federate to me if there was one).
I’m trying very hard not to speculate (and hoping an explanation eventually comes to light), but it’s just weird and concerning to see someone (and their instance) just drop off the map like that.
