Sekitar Tumbangnya Jaringan Operator Indosat

What happened?

Indosat, AS4761, one of Indonesia’s largest telecommunication networks normally originates about 300 prefixes. Starting at 18:26 UTC (April 2, 2014) AS4761 began to originate 417,038 new prefixes normally announced by other Autonomous Systems such as yours. The ‘mis-origination’ event by Indosat lasted for several hours affecting different prefixes at different times until approximately 21:15 UTC.

What caused this?

Given the large scale of this event we presume this is not malicious or intentional but rather the result of an operational issue. Other sources report this was the result of a maintenance window gone bad.
