Synthesia network check

Run this in the browser on the network you plan to use Synthesia from. It shows which Synthesia addresses your network lets through and which it blocks, so your IT team knows exactly what to allow.

A green result means this browser reached the address. A red result means the request was blocked or failed (firewall, proxy, DNS or TLS). The check can't say which. Wildcard entries such as *.mux.com are tested with one real address under that domain. Results only reflect the device and network you run this on.
