Three reports of the same shape: a 503 for anything wider than a few days
before, and since the timeout was raised, a window that sits at 'working'
forever. Both are the same missing thing — nothing said what the transfer was
doing.
The body is now read in chunks and every megabyte is reported. A 503/502/504 is
retried twice, 20 s then 40 s, each attempt announced: LoTW answers 'busy' to a
wide report often enough that other loggers simply ask again. And the deadline
is no longer on the whole exchange, which either cut off a healthy slow download
or hid a dead one for twenty minutes — it is ten minutes to START answering
(LoTW builds the whole report first) and two minutes of silence once it has,
which is the difference between slow and dead.
