Hi Stephan,

I have no problems querying tile servers DNS. Every query is less than
100ms, wuth or without cache. Maybe the problem has gone.

Example:

dig @a.ns.bytemark.co.uk tile.geo.openstreetmap.org.

; <<>> DiG 9.11.3-1ubuntu1-Ubuntu <<>> @a.ns.bytemark.co.uk
tile.geo.openstreetmap.org.
; (2 servers found)
;; global options: +cmd
;; Got answer:
;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 31012
;; flags: qr rd; QUERY: 1, ANSWER: 0, AUTHORITY: 6, ADDITIONAL: 6
;; WARNING: recursion requested but not available

;; QUESTION SECTION:
;tile.geo.openstreetmap.org.	IN	A

geo.openstreetmap.org.	259200	IN	NS	a.ns.openstreetmap.org.
