Apparently the hot patch of adding in surveillance features didn't go as smoothly as hoped :-) I jest of course given the press recently about how good iMessage is at preventing eavesdropping. Keeping services like this alive is pain. Just the other night I got to experience being "down" when as far as my routers were concerned I was "up", some maintenance snafu upstream had my traffic stuck in a routing loop. But no BGP failover because as far as my router was concerned it could talk to its peer. Sigh.

Alternatively, one can imagine a DoS against iMessage (potentially something as subtle as getting a routing table screwed up for some target ISP) with the goal of causing a critical conversation you wish to intercept to be relegated to SMS.
