What is Downdetector?
Downdetector is an online website that allows users of popular services including X (Twitter), Instagram, Facebook, Virgin Media and more to report if they are having trouble with the services.
The site only reports an incident when the number of problem reports is significantly higher than the typical volume for that time of day.
Describing itself on its website, Downdetector is “where people go when services don’t work.”
The website monitors disruptions to various key services including the internet, web hosting platforms, banks, social media and more.
