SaaS Reachability Test: is it down for everyone, or just you?

A free browser check for whether a cloud app is actually down or just blocked on your network. For each service it runs the same reachability check twice - once from this browser, once from an independent Cloudflare edge off your network - then compares: if the edge reaches it but you cannot, the block is on your side; if neither can, it is a vendor outage. Covers Microsoft 365, Google Workspace, Zoom, Slack, and SiteLink myHub.

Privacy: This tool contacts only the listed cloud hosts (Microsoft 365, Google, Zoom, Slack, SiteLink) plus edge.desktest.net, a Cloudflare Worker that stores nothing. The client-side check is a passive no-cors ping - no credentials, no tenant identifiers, no business data. Nothing about you is sent to us. View source to verify the target list. No analytics, no tracking.

Configuration

Driver: Client + edge reachability compare

Takes about 15 seconds. For each service the test pings the vendor host from this browser and asks the Cloudflare edge to do the same; no business data is sent.
