Worth pointing out that the ICANN agreement for all these new TLDs require a website live on whois.nic.<tld> under Specification 4. eg, Google's TLD delegation agreement (https://itp.cdn.icann.org/en/files/registry-agreements/googl...).
Most TLDs will also put live nic.<tld>, but it's not required.
edit: huh, seems like a lot of TLDs are not following their ICANN agreements.
