The OVMS app on my iPhone seems to be unable to connect with the server today (it has been working fine for several months). The blinking antenna icon remains gray, and the battery icon remains at 0%. I note that I can reach tmc.openvehicles.com on port 80, so it is not a network connectivity problem. I checked that one OVMS user sees the same problem.
Apologies for the issue. There was a database error that didn't get automatically recovered from. Server is back online now.
I had problems yesterday and Saturday also. It got me thinking of maybe running my own server. Maybe I could work some high-availability into OVMS? While there will never be more than a thousand or so Roadsters, the other cars could build up.
