I've been running a middle relay on a Raspberry Pi for some time now. Recently, I switched out my first generation Pi for a 2nd generation model B. I installed Tor on the new Pi and moved the keys accordingly. The relay came up again just fine, and has been functioning without errors since.
There's one issue, though. On Globe and Atlas, the bandwidth charts for small time intervals remain empty. The longer intervals (i.e. 1 month and above) do show recent data, indicating that the relay is reporting data sometimes. It seems as if it's just not doing so often enough. For reference, the concerned relay is E1AF83F60B55F4E53A573D4CCDA2C9A58FEC4ADD.
What could be the cause of this?
