[dns-wg] DNS lameness notifications

Hello,

We did also receive that message for nameservers in:
- 3 networks
- 4 class c-subnets
- 4 nameservers (on different servers)

All nameservers where not resolved if I read it correctly. I did check it a
few seconds ago for another time on all nameservers with dig: rDNS records
are correctly returned.

With kind regards,

Dear colleagues,

I was wondering if there is a detailed description of what and how is tested

in order to check the lameness of a server (i.e. how are the names resolved,

timeouts and retransmits of the queries, checks made,....)? Any pointer
would 
be welcome.

The background is that I got notifications ("Unable to resolve nameserver ")

which are most probably wrong, unless the resolving algorithm is very 
delicate... 

Best regards,
Gilles
