DNS Lameness Detailed Statistics

The RIPE NCC runs a lameness check once a month on all DNS servers listed as delegation points within the RIPE NCC delegated zones. If a server fails this test it is retried five times over a period of ten days, at varying times of day. If, after this time, the server continues to fail the test, it is classed as lame.

These charts illustrate the lameness statistics for all servers listed.
