[dns-wg] NREN swapping secondary name-servers?

Hello all,

My name is João Pagaime and I work for FCCN, the
Portuguese NREN that also operates the ccTLD-PT

We're about to move "edu.pt" to a standalone DNS zone,
and I'm searching for a secondary name server outside
AS1930

Is there any NREN interested in swapping seconday
name service?   We can provide for secondary name service
along the lines layed out bellow

Our general requirements guidelines for the edu.pt are
the following:

availability requirements------------------------

It would be nice to have no more than 12 hours down
time every 3 months

that's 99.4% of availability

response time------------------------------------

Less that 140 ms "DNS round-trip-time", measured from the
.PT primary name server

"DNS round-trip-time" on this context is considered
to be the time it takes to answer a DNS query.
We use "dig" to get this value

estimated zone size------------------------------

about 2MB (measured at the secondary server text file)

estimated query load--------------------------------

20 queries/sec

update/transfer strategy-----------------------------

AXFR with notifies (no need to actually respond
to notify. SOA timers suffice)

3 updates every day

zone access policy--------------------------------

restricted

Thank you,
João Pagaime
