IsSiteDown

IsSiteDown lets you check the current site in one click, with official status and incident information where available. If a website is not loading, click the extension icon to instantly check whether the service is operational, degraded, or down. For supported services, IsSiteDown uses the provider’s official status page or status API whenever available, and adds HTTP, DNS, and TLS checks for extra transparency.
