Just half an hour ago China Telecom hijacked one of our prefixes:

Your prefix:          X.Y.Z.0/19:
Prefix Description:   NETNAME
Update time:          2010-04-08 15:58 (UTC)
Detected by #peers:   1
Detected prefix:      X.Y.Z.0/19
Announced by:         AS23724 (CHINANET-IDC-BJ-AP IDC, China 
Telecommunications Corporation)
Upstream AS:          AS4134 (CHINANET-BACKBONE No.31,Jin-rong Street)
ASpath:               39792 4134 23724 23724

Luckily it had to be limited as only one BGPmon peer saw it. Anyone else 
noticed it?
