Internet Intelligence Roundup

4 Mins read

With 2017 drawing to a close, 12 months-give of lookbacks clutter media and the blogosphere like so many leaves on the ground. (Or piles of snow, depending on wherein you are.) Many focus on popular culture, product/film/song releases, or expert sports activities. However, given the focus of Oracle Dyn’s Internet Intelligence team on monitoring and measuring the Internet, we’re going to glance again at huge Internet “occasions” of the beyond yr and how they have impacted connectivity for Internet users around the arena.

Hurricanes Harvey, Irma, and Maria Cause Internet Disruptions

In the past due August and through September, an active Atlantic hurricane season spawned some unfavorable storms that wreaked havoc throughout the Caribbean, Florida, and Texas in the United States. On the Caribbean islands that were the toughest hit via the batteries, the resulting bodily harm changed into great, critically impacting final-mile Internet infrastructure across the complete u. S. This turned into the case in Florida and Texas, though on a far extra localized basis. On September 25, we looked at the influences of these hurricanes on Internet connectivity in the affected areas, noting that while some “center” Internet components remained to be had at some point of these storms way to hardened statistics middle infrastructure, backup energy generators, and comprehensive disaster planning, neighborhood infrastructure – the so-referred to as “remaining mile” – often didn’t fare as properly.


Towards the give up of August, Hurricane Harvey pressured masses of community prefixes in Texas offline. A few days later, Hurricane Irma brought about comparable problems in Florida and Puerto Rico. Sint Maarten was additionally hit extraordinarily difficult by Hurricane Irma, inflicting the unavailability of community prefixes related to the island country. Nearly weeks later, Hurricane Maria slammed into Puerto Rico, inflicting local Internet connectivity problems as it landed. The electricity outages attributable to the storm triggered remaining-mile connectivity to worsen, as we found through a close-to-whole loss of recursive DNS queries from the island. Connectivity endured war every week after Maria, and a recent Internet Intelligence weblog submitted examined the state of Puerto Rico’s post-hurricane Internet connectivity.

Politically Motivated Internet Shutdowns

Nationwide Internet shutdowns for political reasons arguably had their genesis in a January 2011 Internet disruption that passed off in Egypt, which turned accompanied in quick order via similar disruptions in Bahrain, Libya, and Syria. These outages occurred all through what became called the Arab Spring, highlighting the position that the Internet had come to play in political protest and heralding the broader use of countrywide Internet shutdowns to manipulate. A November weblog publishes noted that while these shutdowns occurred in the Middle East and Northern Africa, they have shifted over the last numerous years to end up extra not unusual in sub-Saharan Africa.

Such outages persevered to be the case over this year. In mid-November, Equatorial Guinea’s authorities ordered an entire Internet blackout before an election that was anticipated to maintain the celebration of longtime President Teodoro Obiang Nguema in electricity. This blackout turned into the blocking of getting the right of entry to opposition Web websites, which started in 2013. In September, the government in Togo blocked get access to cellular Internet connectivity amid anti-authorities protests. Following months of demonstrations, Cameroon’s authorities ordered an Internet blackout in English-speak regions beginning in mid-January. This outage lasted till April, and Internet connectivity in these regions was again disrupted in early October, seemingly on the subject of mass protests. As of late November, this newest disruption changed into nevertheless in an area.

Multiple Exam-Related Outages in Syria & Iraq

Students around the arena have long attempted to get an advantage on standardized checks via anything necessary. Of overdue, take a look at-associated facts that have been shared through the Internet, leading the governments of Syria and Iraq to sever Internet connectivity inside their respective nations if you want to save yourself cheating on such tests. The Iraqi authorities employed such techniques in 2015 and 2016, while the Syrian government did so in several cases in 2016. In February 2017, the Iraqi government took down the user’s Internet connectivity for multi-hour periods across multiple days.

As we cited on time, the length of the Internet outages covers the period of the bodily distribution of the examination materials to testing facilities, usually starting at five:00 am on examination day. The outages are supposed to prevent pictures of the questions from the assessments, in conjunction with the solutions, from being shared through social media. Similar outages have been additionally determined in Iraq for the duration of the primary half of-of June.  Syria started a series of national Internet disruptions in late May designed to combat cheating on assessments. The outages took place nine times over the route of weeks. The Syrian Internet was additionally regarded to go offline on July 12. However, we disagree that the outage changed into any instructional trying out taking location in the united states.

Leaked Routes Disrupt Connectivity in Japan and the U.S.

Route leaks arise when a network company inadvertently broadcasts routes to prefixes other than those they’re answerable for. Sometimes a company will announce courses found out from a peer that had not been purported to be shared further. In different instances, the leaking issuer “masquerades” because of the route’s starting place, while greater significant leaks occur when an issuer proclaims a complete routing desk. Depending on the kind of leak and how extensively those leaks are propagated throughout upstream vendors, the remaining impact is that site visitors to affected network prefixes are redirected, misplaced, or intercepted; the severity can vary from not noted to catastrophic. Blog posts we published in 2015 and 2014 looked at several examples of route leaks and their impacts, while any other 2015 publish looked at the effect of a routing leak on Google services availability.
