I noticed this at the time as I was configuring a firewall and my ISP (Rogers cable) began to supply an invalid address to the WAN side of the box. 192.168.100.1 is definitely not an address that Rogers would normally issue. Calls to tech support returned fast busy. All calls outside the town of Portugal Cove returned fast busy. I went to sleep knowing I could reach the local firehall if I needed to.
Things were chaotic in St John's; virtually ALL telecom was affected. There was a fire in a power cable tray on the 2nd floor of the (6 floor) Allandale Rd central office and the tech on-site decided to cut off power to the entire building to fight it. This prevented normal back-up systems and knocked out cell service, most of 911, long distance and internet service to the mainland.
St John's is the capital and largest city on the Island of Newfoundland off the east coast of Canada, which has a population of more than 500,000. This is the second major outage I have experienced here. The first was due to simultaneous cuts to the fibre optics cable crossing the island. That one occurred during a labor dispute.
