Same alert for me on two of my prefixes. Still looking into it.

I received a similar notification about one of our prefixes also a few

also couldn't hit the websites for either AS, either.

So I setup BGPMON for my prefixes and got an alert about someone in
Thailand announcing my prefix.  Everything looks fine to me and I've
checked a bunch of different Looking Glasses and everything announcing
correctly.

I am assuming I should be contacting the provider about their
misconfiguration and announcing my prefixes and get them to fix it.  Any
other recommendations?

Is there a way I can verify what they are announcing just to make sure they
are still doing it?

Here is the alert for reference:
