Hello,
I have a T1 that keeps dropping. My clients need to
connect to my servers in house. I want to add a DSL
circuit from a different provider for redundancy. My T1
has one class C range of IP's, the DSL will have another
range of IP's. To make my plan of redundancy work, I was
thinking that if i tweak my Zone file to have two
weighted "A" records pointing to the same server on two
different circuits this would solve my name resolution
issues i would have when my T1 goes down.

Example:

myserver A 10 65.222.175.3
myserver A 1 65.195.3.4

IS THIS POSSIBLE?

if not is there another solution?

I would be nice, but you can't do that with A records. However, IE (and
others) can help you out here. You can create both A records with the T1
first. Turn on round-robin and netmask ordering in the dns server. Now
clients should get both records in the answer in order. IE will try the
first one. If that fails to connect, it will try the second one, etc. This
is ok, but not 100% because other dns servers that cache your records could
handle the ordering differently. hth

Not really, maybe try what William suggested.

My thoughts are on the T1. If the provider can't get it to stay up, get rid
of them and go with another vendor. Period. You should have an SLA with the
contract stating it's supposed to be up at least 99% of the time. Usually
T1s are a priority circuit and have a 2 hour call turn around for a trouble
ticket. I've had them out at my place 11pm on Sunday nites when I initially
had a problem upon turn up (when I first got it). Once they fixed it, it was
up all the time. That's with Qwest for almost two years without a glitch.
Constantly up, never down, rain, snow, sleet or hail. :-)

Go with someone reliable and you won;'t have to worry about this.
