Hi, I am from india and can’t see USA and Brazil location in remote test labs. Are they permanently down or am i missing something to configure from my end? Here is screenshot from my account.
Not every device is available in every country. 
There are no Galaxy A devices available in the lab in the USA or Brazil, unfortunately. Actually I can’t see any mobile devices available in the USA?
.
I believe Brazil is dealing with ongoing power shortages and that may cause servers being down temporarily.
The USA Remote Test Lab is temporarily offline while it deals with a security issue that does not affect other RTL sites. I do not expect the US RTL to return soon.
I will check on the A devices in Brazil.
