That's the same time my connection died today too...What's really strange is that when the ADSL went dead, I logged into my Mikrotik router and noticed that my WAN connection (the PPPOE connection) was being flooded by ICMP pings from a Telkom IP address. Traffic was trying to go out via the WAN but no incoming packets were coming back EXCEPT for these ICMP packets from that Telkom IP address. So the PPPOE connection was still up at the time of the outage. Very strange. Also strange that it happened at exactly 12am.
