We have additional questions for ICANN org. Please see highlighted below

We have found several error messages in using the tool referenced below:

The requested second-level domain was not found in the Registry or Registrar’s WHOIS Server. (the domain name was confirmed to be registered with the registry)

Sorry, but the Registry or Registrar WHOIS Server responded with a rate limit message due to high query volumes or has closed the connection without a response. Please try your request again later.

ICANN received a timeout while querying the Registry or Registrar’s WHOIS Server

Are these error messages created by ICANN or do they come directly from the Registrar or Registry?

Does ICANN track how often these error messages are presented in response to a WHOIS query?
