[HOT] Map-a-thon getting 509 Bandwidth Exceeded error

Hi Nicholas,

My assumption is the machines are all using the same ip. I faced this in
the past in Haiti, but with JOSM and the classic download tool. The mirror
download plugin is less limited, but I do not know if there is a bypass for
iD.

Sincerely,

Severin
