Webapp sends 'Wire is so much nicer with internet!' every now and then to make sure it is still able to talk to the server. However because server doesn't respond to this message, in some cases it is impossible to detect if webapp is actually offline.

See this message for details: wireapp/wire-desktop#1129 (comment)

Please make Wire respond with some string like 'Indeed it is' on each such ping request, so that it's possible to improve webapp.
