Hey,

This does still work as i can see domains are updating however it is limited to some domains due to how the whois server responds and doesnt provide the information.

It has been noticed that before some whois servers block specific networks which can cause these to not update. One thing is to check you allow port 43 outbound as this is used to connect to the whois servers.

As a project im not sure how useful these expiry dates are to everybody espically when they only allow a limit amount of TLDs.

Regards,

Trevor
