We are currently experiencing an intermittent issue with domain check availability service on Order box for most of the TLDs.
Any check availability calls made via API or Supersite would either not respond or may yield an error.
Supersite would show the search results as unavailable and API would return an unknown error.
Our development team is currently investigating this issue to get the service back up at the earliest.
In the meanwhile, your patience is highly appreciated.
