A host of websites including LinkedIn, Zoom and Downdetector went offline on Friday morning after fresh problems at Cloudflare. Cloudflare said shortly after 9am UK time that it was “investigating issues with Cloudflare Dashboard and related APIs”, referring to application programming interfaces. A number of websites and platforms were down, including the Downdetector site used to monitor online service issues. Users reported problems with other websites including Zoom, LinkedIn, Shopify and Canva, although many are back online. Cloudflare provides network and security services for many online businesses to help their websites and applications operate.
