xxcancel.com (just add an x to xcancel.com) will redirect you to a working instance!

As promised:

https://github.com/skorokithakis/detour, running on https://twit.0r.cx.

Just replace x.com with twit.0r.cx.

Example:

The LibRedirect browser extensions lets you configure a list and quickly hot between, but it doesn't check whether they are up before redirecting you to one of them iirc

There was a service I discovered that was set as a default in this app: https://github.com/circumspace/linkahest

Unfortunately it also shut down a few days before the nitter takedowns.

I mean, I was just thinking of writing one in a few lines, so there will be one in a few minutes.
