- ? Is .uk growing or shrinking?
- .uk has grown by 49.10% over the last year (+272,862 domains).
- ? Where does the .uk domain count come from?
- We ingest ICANN CZDS zone files and Certificate Transparency logs continuously and snapshot the per-TLD count once a day. A .uk domain is counted as active if it appeared in a zone file in the last 2 days, or - where no zone file is published - if a certificate was issued for it in the last 12 months.
