BGPMON Alert Questions
I got a bounce from Indosat saying:
"Dear Senders,
Thank you for your email, started March,1st 2012 email address for
correspondence with Indosat IP Support & All Support INP will be change and
not active with detail information as follows :
1. Correspondence and complain handling for Indosat Corporate customers
(INP, IDIA and INIX services) please kindly address to :
corporatesolution at indosat.com (Service Desk MIDI Indosat Corporate Solution)
2. Correspondence and coordination for upstream and peering purpose please
kindly address to : SNOCIPSurv at indosat.com (SNOC IP Surveillance)
Thank you for your kind cooperation and understanding.

Perhaps the ?SNOC IP Surveillance? address is better?
For CAT Thailand, the contact details I have are:
NOC call center
CAT Telecom
Tel: 66 2 104 2382
FAX: 66 2 104 2281
e-mail: cusserv at cattelecom.com
As someone mentioned, English may be an issue, especially at this time of
the morning over there.

Contacted ip.tac at indosat.com about this, I urge others to do the same.
