Internet outages: lessons from Cloudflare's Q3 report

Cloudflare, which carries more than a fifth of the world's web traffic, counted 49 major internet disruptions between July and September 2026. Government shutdowns made up 19 of them, power failures 14 and natural disasters five. The causes it lists are the same things that take an ordinary office offline: power cuts, one weak link and damaged cables. A small backup plan covers most of them.

What went wrong around the world

Power was the clearest pattern. When the electricity goes, routers, mobile towers and data centres go with it. Cloudflare saw power-related outages in 10 countries during the quarter.

One failure point can take out a whole country. In Honduras, a power failure at a single building where networks swap traffic hit at least 11 internet providers for about three hours. A few providers with links outside the country stayed up.

Data centres need cooling as well as power. On 13 August a cooling failure at one data centre in the US city of Phoenix almost completely cut traffic from a web hosting company based there.

Cable damage from earthquakes and floods caused longer outages, in one case more than four days. Countries with a strong record, such as the US, Japan and Portugal, also had outages, so nobody is fully safe.

The good news is that most disruptions were short: 14 recovered in under an hour and 16 more in under three hours.

What this means for your office

The same weak spots exist on a smaller scale in every office. A router without backup power, one fibre line, or a website and email that both depend on one provider can stop work for hours.

What to do

1. Put the router, fibre modem and main network switch on a UPS, so a short power cut does not drop the connection.
2. Keep a backup line. A mobile broadband router or a phone hotspot is enough for email and payments while the fibre is down.
3. Note your ISP's fault line and account number somewhere you can find without the internet.
4. Keep your website and email with a host that runs backup power and cooling in its data centre, and ask how they handle outages.
5. Save important files in a cloud drive as well as on office PCs, so staff can keep working from home if the office loses its connection.

How SyncTech can help

Your website and email do not have to sit in the office. With business web hosting they stay reachable for customers when the office loses power or fibre.
