I’m working on testing an R package in development, and have always used R Mac Builder as one test environment. However, today upon calling devtools::check_mac_release(), I get this error:

> devtools::check_mac_release()

Error in devtools::check_mac_release() : 
  Bad Gateway (HTTP 502). Failed to Uploading package.

Does the Bad Gateway (HTTP 502) mean R Mac Builder is down, or is there something wrong on my end?
