No, this service is still supported, though note that there have been a
number of exploits published since this test was derived which means
that results previously stated as "safe" are now less clear-cut.

For questions/issues with OARC services, the best place to request help
is <admin at dns-oarc.net>.

We will investigate, though this may take a little longer than usual due
to the upcoming workshop and planned systems maintenance over the next
few days.
