The AP reports “A statement from the country’s Telecommunication Regulatory Commission said they were unable to ensure service after their data center was attacked Thursday by demonstrators, who set fire to some equipment. The Associated Press was not able to independently verify this.” However, the near-complete outage observed by Trinocular (as seen in the figures above) seems inconsistent with problems at a single datacenter.
Update July 19, 22:28Z:ISOC Pulse has a post about this outage, and reports that “In a press event on 18 July, Bangladesh minister for posts, telecommunications, and information technology, Zunaid Ahmed Palak confirmed that the government had ordered the shutdown. “
To add about the root cause, the Deccan Heraldpublished an article from Reuters quoting Zunaid Ahmed Palak, junior information technology minister, as saying to reporters: “Mobile internet has been temporarily suspended due to various rumors and the unstable situation created…. on social media” on July 18. Today, Reuters quoted Palak as saying that “broadband internet would be restored by Tuesday night but [he] did not comment on mobile internet”. This statement is consistent with the country-wide outage we observed, and the prior statement suggests the outage was a request of the government.
Update July 24, 13:00Z (19:00 in Bangladesh): It looks like nearly all Bangladeshi networks are now back online.
Update July 25:The July 25 episode of The Briefing, an Australian news podcast, discussed the Bangladeshi outage and its impact, interviewing us about what we saw.
Starting on April 21, 2024, we observed a large Internet outage in the country Georgia. More than half the IP blocks in large parts of the country have become unreachable from the U.S., with the problem persisting for several days so far.
News reports indicate that Spectrum had a cable cut.
Trinocular showed an outage from 8:40am to 1:05pm (mountain time zone), with an smaller initial outage starting at 7am (2023-11-04t15:40 to t20:00 UTC, possibly starting at 14:00 UTC). This outage was quite severe, affecting more than 40% of the local networks that we monitor.
Cable cuts are hard to deal with, and we’re happy that they were able to restore service relatively quickly!
These outages were nation-wide, apparently affecting most of Italy. However, it looks like they “only” affected 20-30% of networks, and not all Italian ISPs. We’re happy they were able to recover so quickly.
This event shows the importance of global network monitoring.
It’s big! Maybe 30% of Toronto and southern Ontario networks, plus a lot of outages in New Brunswick.
Ontario:
New Brunswick:
An update: Newfoundland also sees a lot of outages. Quebec looks in pretty good shape, though.
And it’s lasting a long time. It looks like it started at 5am Eastern time (2022-07-08t09:00Z), it it has lasted 9.5 hours so far!
We wish Rogers personnel and our Canadian neighbors the best.
Update at 2022-07-09t06:15Z (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.
Update at 2022-07-09t21:10Z (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.
Erica Stutz completed her summer undergraduate research internship at ISI this summer, working with John Heidemann, Yuri Pradkin, and Xiao Song on her project “Visualizing COVID-19 Work-from-Home”.
In this project, Erica developed a new Covid-19 Work-From-Home website combinng Xiao WFH data with our existing outage website, and adding new interactive drill-down methods to display additional information to the user.
We hope Erica’s new website makes it easier to evaluate COVID-19 WFH changes, and we look forward to continue to work with Erica on this topic.
Erica worked virtually at USC/ISI in summer 2021 as part of the (ISI Research Experiences for Undergraduates. We thank Jelena Mirkovic (PI) for coordinating the second year of this great program, and NSF for support through award #2051101.
