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.
