Snapchat is down for users across the world.

The disappearing message service has acknowleged that "some" users are having problems as says that it is "working on a fix now".

The problems seem to have been present for some time, without a fix.

Various parts of the service seem to be down, and most of its primary features are broken — including logging in and loading and sending snaps.

Users on Twitter posted about their irritation as the app went down, complaining that they now had little to do or had to turn to other social networks.

The service has been having intermittent problems for much of the week, according to website Down Detector. Most of them have been fixed within a couple of hours.
