I just got the same alert for one of my prefixes one minute ago. On 4/2/2014 2:59 PM, Frank Bulk wrote:
I received a similar notification about one of our prefixes also a few minutes ago. I couldn't find a looking glass for AS4761 or AS4651. But I 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:
