RIPE NCC–which has been signing its own zones since 2005–this week released updated global maps showing the progress of DNSSEC deployment.  The report noted: “When the root zone has been signed in June 2010, this acted as a catalyst for TLD operators to deploy DNSSEC on their side. We have seen a gradual but significant increase in signed TLDs since then.”

The RIPE map of country code top-level domain DNSSEC deployment in Europe–one of several in the post–is shown below.  Green indicates ccTLDs that have deployed to date; yellow indicates those with plans to deploy.
