Here's a telnet attempt:

  $ telnet heroku.com 22
  Trying 50.19.85.154...
  Trying 50.19.85.156...
  Trying 50.19.85.132...
  telnet: Unable to connect to remote host: Connection timed out

Same for GitHub (no problem):

  $ telnet github.com 22
  Trying 204.232.175.90...
  Connected to github.com.
  Escape character is ']'.
  Connection closed by foreign host.

Here's SSH attempt:

  $ ssh git@heroku.com -v

  Hi littlepea! You've successfully authenticated, but GitHub does not provide shell access.
  Connection to github.com closed.

My public key is added on heroku and is correct. It was working all the time until today and anyway I would get a "Permission denied" error not a timeout then:

  $ heroku keys
  === little_pea@list.ru Keys
  ssh-rsa AAAAB3NzaC...9Asmascw== slam

My access to heroku.com host is fine too:

  host heroku.com
  heroku.com has address 50.19.85.156
  heroku.com has address 50.19.85.154
  heroku.com has address 50.19.85.132

  heroku.com mail is handled by 10 aspmx5.googlemail.com.
  heroku.com mail is handled by 10 alt1.aspmx.l.google.com.

Otherwise the toolbelt is working as well, I can create application, add config values and so on, only Git has a problem.

I have a same problem, god.
