What we found

A fair credit to ask for

$16.92

$4.67 for 2 days with half an hour or more of outages, at a day's share of your monthly price; $12.25 because the median speed was 82% of the typical speed you pay for.

This is our estimate of a fair ask, not an amount your provider has to pay. Many providers have their own outage credit policy, so ask them to apply it if it gives more.

How this was measured

Every five seconds, ISP Watchdog checks that the home router answers and that the internet answers, using Cloudflare's 1.1.1.1 and Google's 8.8.8.8. Two failed checks in a row, about ten seconds, count as an outage. If the router kept answering while the internet didn't, the outage was past the home, on the provider's side.

Speed tests run on a schedule through the day and evening, about 5 a day, against a Cloudflare data center near you. Each test downloads and uploads over several connections at once for up to eight seconds, stopping sooner once the speed holds steady, and leaves out the first moments while the connections speed up. Lag is a ping to Cloudflare's 1.1.1.1, first while the line is quiet and again during the download and upload.

Tests are skipped when this PC is already using the internet heavily, when a VPN is on, and when the PC isn't on the home network. The report uses medians, the middle value, so one unusual reading can't swing the result.

Wi-Fi and the PC's own network link can limit a test. Each test records how the PC was connected so you can see this, and tests that the PC's link held back are left out when there are enough others.
