I am seeing this as currently working from multiple locations for both
v4 and v6, though our legacy testers do sometimes fail or have
connectivity issues occasionally.

Note that the best place to report issues with OARC services is
<admin at dns-oarc.net>, please let us know if you are still having
problems and we will investigate further.
