For about a month when using the API to register biz domains stably and continually issued "system_busy". At any time of day. For com/net there is no such problem.
P.S. Error only in API_1 version.

Accounts with higher spending have priority, which may be the reason why you are receiving the "system_busy" and/or "error, problem with connection to main server" messages.
Whenever I try to use the API between 19:00 and 20:00 UTC I get the "system_busy" error, it happens every single time. Is there some sort of priority given to other users?
