Yup. A few Multics sites are publicly accessible; the one at the Living
Computer Museum has a guest account, a few others one can get an account if
one asks the site administrator nicely. Some amount of Multics maintenance
has been restarted.

Multics was the immediate predecessor of Unix, and one can certainly see
some of the influence, though of course many of the details are different.
Failed only in the sense that the Labs withdrew from the project.

The multicians.org site has a lot of good information on Multics and what
ultimately become of it. (jcs probably knows this already; I'm writing this
more for general information of those who may not have been following these
developments.) The TL;DR was that a smallish number of sites eventually
installed Multics and it was a moderate success for Honeywell, but for the
reasons that have been mentioned (failure to market, lack of management
understanding, tied to a decomposing architecture well past its prime) it
never carved out more than a niche.
The real mystery is what it's running on. Multics originally ran

The last working hardware installation was shut down in, I think, 2000. An
DPS8/M emulator has been built on top of the SIMH framework, and is what
folks are running Multics on. Some more details are here:
