Jeff,

Thanks again for responding.  To take you one step further into the topology here, there is a router/firewall cluster in front of the DNS server, which is also a dns server itself, forwarding queries to the machine we're discussing.  The firewall does prefer the server in question, however it also fails over to other alternate servers found on the Tier 2 list during such times the preferred server is not available.  Thus, I am confident that there is enough redundancy assembled to set any questions about "server uptime" aside.  If I may bring you back to the issue at hand, outage for the 74.212.172.171 address has been caused by an issue at the physical layer.

i will attempt to register another server on the wiki, and for anyone else reading this, hopefully this will give you at least one reason more to use one of my IPs.

thanks, enjoy the rest of your evening,

You can always register another server on the wiki, however I would advise against it.  My reasoning for this comes from considering a normal user in your area, seeing to distinctly different IP addresses, would naturally assume these are two different servers - and some might happen to grab your two IP addresses as their primary and secondary dns sources.  Now what happens if you actually have a server issue?  Those users lose all DNS access in one shot, without ever realizing what happened.

I also have two separate IP addresses available to my servers, from two different ISPs, however I have chosen not to list my second IP specifically to avoid this kind of confusion.  You could of course list the alternate IP in the notes for your T2 server on the wiki page, and allow those who are looking a chance to use the alternate, but by including both addresses under the same server listing, you make it obvious that both addresses point to the same location and avoid the chance of someone mistaking it for multiple machines.

Sorry, its late here, and I think I'm rambling.  I hope that makes sense, but if not, I'll try to explain better tomorrow.

Jeff,

Thanks for the response, this IP address has been a permanent addition to the server's related network topology; it is part of a redundancy plan that was put in place some time ago for this exact reason.

Being that this is currently the only server for OpenNIC dns services I operate, and users normally use at least 2 dns servers for standard lookup procedures, I assume no one electing to use my server has even noticed.  Because bigger is usually better when discussing DNS, I can only perceive this as a benefit to the community.

Thank you for explaining how the new automated tier 2 list works, I was already aware.  Assuming you included that information for the same reason I suggested listing the redundant ip address of the server, I ask that you please reconsider your decision for including the 208.125.2.59 address in your published list of Tier2 severs available.

Thanks,

It is good to have this information out there for general use, however
my question would be... is it reasonable to list two separate IP
addresses pointing at the same server?  Is it worth the effort to create
a second listing?  Will this second IP be temporary, or is it a
permanent connection?  Anyone who is using your server as their primary
may wish to change their settings, but I think most people will just
ignore the problem until your listed IP comes back online again.

Just as a refresher for how the automated system handles T2 outages --
If your server fails for 7 days in a row, it will be removed from the
general listing, but will continue to be tested.  Once your server is
online and stable for 2 days, it will automatically reappear in the dns
zone files and on the wiki.

Hello, My listed Tier-2 server in New York has had outage for a few days now because of the link. However, the alternate IP address for this server _is_ up. Technically, I am requesting a second listing while apologizing for my outage at the same time. I expect the link to be back up in the next couple weeks (fffffff-) the primary address for the server is 74.212.172.171 the alternate address is 208.125.2.59 < this IP should be added, not replace the above address. In response to recent dialogue regarding server hardware and links, I am using Business Class links or better for both addresses and server hardware is not "off-the-shelf" / bargain / throw-away hardware. The dns server runs on a virtual machine with sister guests that are serving enterprise sites/software. Thank you for your time and understanding, I am sorry for not submitting the secondary IP earlier. mike--
