Tried the recipients mailbox is full, but it looks like all of the bgpmon alerts have cleared. On Wed, Apr 2, 2014 at 1:40 PM, Aris Lambrianidis <effulgence@gmail.com>wrote:
Contacted ip.tac@indosat.com about this, I urge others to do the same.

Hi All,
I am a network admin for Aware Corporation AS18356 (Thailand), as mentioned in the alert. We operate a BGPMon PeerMon node on our network, which peers with the BGPMon service as a collector.
It is likely that AS4761 (INDOSAT) has somehow managed to hijack these prefixes and CAT (Communications Authority of Thailand AS4651) is not filtering them, hence they are announced to us and are triggering these BGPMon alerts.
I have had several mails to our NOC about this already and have responded directly to those. I suggest contacting Indosat directly to get this resolved. AS18356 is a stub AS, so we are not actually advertising these learned hijacked prefixes to anyone but BGPMon for data collection purposes.
Thanks.
Regards,
Andrew Ashley

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:
Your prefix: 8.37.93.0/24:
