.io, .ai, and .co always return as registered

[choxi]

I tried the following:

parser = Whois.whois("stratocumulus.ai").parser
parser.available?
# => false
parser.registered?
# => true

But the domain is available: https://iwantmyname.com/?domain=stratocumulus.ai. I get the same issue for .io and .co domains. Are the parsers out of date?

This problem (with .co, at least) still exists... Here's an example of the data being returned by the parser for a non-existent domain:

=> #<Whois::Parser:0x087b2c00 @record="No Data Found\r\nURL of the ICANN Whois Inaccuracy Complaint Form: https://www.icann.org/wicf/\r\n>>> Last update of WHOIS database: 2019-09-14T00:07:09Z <<<\r\n\r\nFor more information on Whois status codes, please visit https://icann.org/epp\r\n\r\nThe above WHOIS results have been redacted to remove potential personal data.

In some limited cases, domains that might appear as available in whois might not actually be available as they could be already registered and the whois not yet updated and/or they could be part of the Restricted list. In this cases, performing a check through your Registrar's (EPP check) will give you the actual status of the domain. Additionally, domains currently or previously used as extensions in 3rd level domains will not be available for registration in the 2nd level. For example, org.co,mil.co,edu.co,com.co,net.co,nom.co,arts.co, firm.co,info.co,int.co,web.co,rec.co,co.co.\r\n\r\nNOTE: FAILURE TO LOCATE A RECORD IN THE WHOIS DATABASE IS NOT INDICATIVE OF THE AVAILABILITY OF A DOMAIN NAME.
