Several people asked me off list for more details, here is what I have regarding it.

This morning a tier2 isp that connects to our network made an error in their router configuration causing the route leakage. The issue has been addressed and we will be performing a full post mortem to ensure this does not happen again.
While investigating the issue we did find that the noction appliance stopped advertising the no export community string with its advertisements which is why certain prefixes were also seen.

+2, after the morning coffee sunk in and helpful off list replies I can
finally see it's probably not INDOSAT involved at all.

FYI, the more specifics are still active:
