This test is designed to examine the reachability of Telegram’s app and web
version within a tested network.
More specifically, this test attempts to perform an HTTP POST request, and
establish a TCP connection to Telegram’s access points (DCs), as well as an
HTTP GET request to Telegram’s web version (
web.telegram.org) over the
vantage point of the user. The test is triggered as blocking when connections
to all access points defined in the [test]
Based on this methodology Telegram’s app is likely blocked if any of the
Telegram’s web version is likely blocked if the following applies:
- HTTP(S) GET requests to
web.telegram.org do not send back a consistent
response to OONI’s servers.
