A year ago, in my “Last Month in Internet Intelligence: February 2019” post for Oracle’s Internet Intelligence blog, I noted that “February was a surprisingly quiet month for Internet disruptions.” Interestingly, that appeared to hold true a year later, with fewer major disruptions observed than in prior months. In addition, the disruptions covered this month had a more limited set of causes — a DDoS attack, network maintenance, and cable/fiber issues — no power outages in Venezuela or wide-scale Internet shutdowns in the Middle East as have been seen in prior months.Continue reading →
January 2020 brought the start of both a new year and a new decade, not to mention the continued deployment of satellite constellations that will be used to provide broadband Internet connectivity around the world. While space-based Internet connectivity holds promise for the future, Internet connectivity delivered through terrestrial and submarine infrastructure saw its fair share of problems throughout the month. In January, Internet disruptions caused by earthquakes, power outages, network maintenance, government direction, and cable cuts were observed.Continue reading →
Internet-related media coverage in December tends to be e-commerce related, with discussions about how retail sites performed (or failed to) on Black Friday and Cyber Monday, followed by complaints about problems downloading software updates or games, and registering new connected devices after the holiday presents are unwrapped. However, when Internet disruptions occur, that coverage shifts to highlight the problems caused by the disruptions.
This final Internet Disruption Report post for 2019 is a long one, covering disruptions caused by a DDoS attack, power outages, cable/fiber/network issues, and government direction. Some countries make multiple appearances in this month’s report, and some have been featured in multiple reports throughout the year. In addition to observed disruptions, we also review Russia’s reported Internet disconnection test, as well as a few additional related observations.Continue reading →
In November, many of us in the United States think about the Internet in terms of having to fix the connectivity problems at a relative’s house while visiting them for Thanksgiving, or using it to escape from those same relatives for a few minutes by browsing social media or watching a video. However, across the rest of the world, the connectivity problems seen in November weren’t the kind a quick router reboot would solve. Blackouts caused Internet disruptions in Curaçao and Venezuela, fiber/cable issues caused problems in Haiti, Venezuela, Liberia, Sierra Leone, and the Gambia, and routing issues disrupted connectivity in Indonesia and Ecuador. However, the most significant Internet disruptions in November were week-long government directed shutdowns in Iraq and Iran.Continue reading →
Notable Internet disruptions observed in October were generally short-lived and due to power outages, cable cuts, and other acknowledged but unexplained network issues. However, the most significant disruption observed during the month occurred in Iraq, and was due to a government directed shutdown of Internet connectivity for over a week in response to violent protests. Total losses due to this shutdown were estimated at nearly 1 Billion USD.
(Apologies for posting this month’s update a few weeks later than usual – sometimes life and work get in the way of blogging…)Continue reading →
September… when school is back in session, the leaves begin to change, and stable Internet connectivity apparently remains elusive in many countries. Although the Internet disruptions observed around the world this during last month were not due to the change of seasons or the start of school, their underlying causes were very familiar, including power outages, national exams, severe weather, network issues, and DDoS attacks.Continue reading →
The August 1994 issue of WIRED Magazine hardly hinted at the coming ubiquity of the Internet, featuring articles on CD-ROM games and reviews of the Apple Newton. Commercial Internet services were very much in their infancy at the time, with the issue containing just a few advertisements for nascent Internet Service Providers, such as the one shown below. Twenty-five years ago, Internet disruptions were more likely to be caused by overloaded modem banks or congestion at one of the few peering points available at the time.
Today, Internet connectivity is significantly more ubiquitous, faster and less expensive (in most places), and generally reliable. With increased Internet availability and usage, however, disruptions become more noticeable, and impact a significantly larger population of users. In August, we observed Internet disruptions around the world due to power outages, national exams, and network issues. Several government-directed disruptions were widely reported as well, but were not easily observable in monitoring tools.Continue reading →
