News reports (for example, at the Verge<\/a> and Slashdot<\/a>) mention a large outage in Rogers, a major Canadian telecommunications provider.<\/p>\n\n\n\n

We see lots of evidence for this in our Internet outage detection system<\/a>.<\/p>\n\n\n\n

It’s big!<\/strong> Maybe 30% of Toronto and southern Ontario networks, plus a lot of outages in New Brunswick.<\/p>\n\n\n\n

Ontario:<\/p>\n\n\n\n

\"\"<\/a>
Internet outages in Ontario, Canada. The largest circle represents about 6500 \/24 network blocks down near Toronto, about 30% of the \/24 blocks in that area. See details on our outage website.<\/a><\/figcaption><\/figure>\n\n\n\n

New Brunswick:<\/p>\n\n\n\n

\"\"<\/a>
Internet outages in New Brunswick, Canada. The largest circle here represents 196 \/24 network blocks down near Moncton, more than 45% of the \/24 blocks there. The red circles are areas where most or all network blocks are currently out. See details on our outage website.<\/a><\/figcaption><\/figure>\n\n\n\n

An update: Newfoundland also sees a lot of outages. Quebec looks in pretty good shape, though.<\/p>\n\n\n\n

And it’s lasting a long time<\/strong>. It looks like it started at 5am Eastern time (2022-07-08t09:00Z), it it has lasted 9.5 hours so far!<\/p>\n\n\n\n

We wish Rogers personnel and our Canadian neighbors the best.<\/p>\n\n\n\n

Update at 2022-07-09t06:15Z<\/strong> (2:15am Eastern time): Toronto is doing much better, with “only” 10% of blocks unreachable (22808 of 21.5k in the 43.8N,79.3W 0.5 grid cell). New Brunswick and Newfoundland still look the same, with outages in about 50% of blocks.<\/p>\n\n\n\n

Update at 2022-07-09t21:10Z<\/strong> (5:10pm Eastern time): It looks like many Rogers networks recovered at 2022-07-09t05:15Z (1:15am Eastern time). This includes all of New Brunswick and Newfoundland and most of Ontario. Trinocular has about a one-hour delay while it computes results, so I did not see this result when I checked in the prior update–I needed to wait 15 minutes more. <\/p>\n","protected":false},"excerpt":{"rendered":"
