I received a complaint from a friend that one of my stations was offline, but when I tried it, it was fine.
It turned out that he'd used a mixed case version of the station name. (Iflinder3 vs IFLINDER3)
It appears that if you use a mixed case version of the station name it brings up the correct station but it reports it as offline, (but NOT ALWAYS). Not an important bug, but a strange one.
Try these on your phone and see what you get:
