Blackberry messenger ' no coverage ' then ' temporarily unavailable ' notifications.

This morning bbm was working normally, went back an hour or so later and a blue screen appeared with the exact message.. ' Oops move to an are with with better coverage, or try connecting to a Wi-Fi network. ' of course I'm using my phone in the usual places where i always have coverage tried wifi same message, I uninstalled then re-installed and the same error but managed to get onto the sign in Blackberry ID part so signed in and then a message appeared BB ID ' Service Temporarily unavailable ' have no idea whats going on i have great coverage, wifi have rebooted turned phone of and on deleted then installed app few times nothing? help had no issues til now.

Is it working now? Was it just maybe a server issue?
