lately I have noticed TCP response over IPv4 can be quite slow for flora.web.telegram.org, which is breaking web.telegram.org https://flora.web.telegram.org/apiw1 HTTP POST requests.
$ curl -so /dev/null https://flora.web.telegram.org -v

It looks like this affects some source IPs more than others. Is there a way to contact Telegram to troubleshoot?
