Note, having been the person behind the implementation and support of
UTRS at TC, most of you know I am no longer there and have nothing to
with it any longer.  It is still running and I believe TC still
technically supports it, but I'm sorry to say I don't believe it has
lived up to the dream and seems unlikely to.  I even ended up disabling
it here at DePaul. I'll take the blame for the lack of success and I'm
sorry to TC if this undermines the effort further, but I know I'm not
alone in this sentiment.

I know of at least one other group that was interested in trying to
recreate a version of UTRS elsewhere and I've suggested doing something
new and related, but other things have since taken over my time.
inter-AS flowspec was what I had plans to to add to UTRS next, but left
before I could safely deploy it. To relay flowspec messages successfully
and safely I would argue is not as simple as just "turning it on".
