I never made the DNS request myself, but I might have rubberstamped a 
request from you without looking closely at it. My fault, not yours.

We have had this discussion before, so let me repeat the rules. The home 
page for ntp.org lives here and nowhere else (but, see below). The 
software itself, including archives and the project page live here and

be mirrored anywhere else and any claims for authenticity 
notwithstanding.. But, if you get it from here via ntp.org, it's the 
real stuff and there are professional folks here responsible for the 
care and upkeep of the hardware, including tens of terabyres of RAID 5 
and huge backup farms.

I've always been happy to have the public services project hosted 
elsewhere. All I care about is the point of entry - the home page - and 
the software and archives. If you choose to host the home page elsewhere 
for redundancy, you must promise that the mirrored pages are exactly the 

The host machine for ntp.org is one of several virtual machines on our 
huge departmet server farm. We are in the midst of a software  upgrade 
that may have taken the farm down for a few hours. We have had a couple

used to use a DS3 circuit to the ISP, but I can see it's now faster than
