That would have to be the IERS.

I do not believe that any of the IERS bureaus have internet
connections and servers which are anywhere near robust and redundant
enough to make that a reliable service.

There is a lot that could and should be done.

The USNO branch of the IERS issues two files with predictions about
earth orientation every Thursday.
It is not widely known that last July on the Thursday following the
Daniel Gambis announcement one of those files acknowledged the leap
second we just experienced, and the other did not.
This was fixed with a new release which happened by Friday.

(Despite some NTP servers which reportedly still have not acknowledged
the leap second, I think the overall indications are that the NTP
network did better than 50 %.)

The existing IERS system is dysfunctional.
