Hi,We're looking for a contact, *that works*, to get in touch with AS4637 (Telstra/HK) about some hijacking or router sickness.
BGPmon has been reporting an hijack of AS3's subnet 18.29.238.0/23.After being contacted by AS3, we went over the advertisement with AS29909 and AS16532 to be sure.
Then we tried getting in touch with AS4637 (Telstra/HK) but it went nowhere at this point.
PS: If anyone has better observations that would be greatly appreciated.
----- Context:A few times this month, BGPmon reported an hijack of 18.29.238.0/23 (AS3).
For this hijack I see AS4637 (Telstra/HK), AS3257( GTT) AS29909 (MOO) and AS16532 ( (which are peers I know and I'm in contact with).
And I'm pretty sure AS3257 (GTT ) is in the same boat as us, as they're not the one advertising those routes to AS4637
AS16532 found it to come from AS4637 as you can see from this ColoAU LG output below
