Trying to set a simple fail over when site A is active and site B is
standby. When A fails all traffic goes to B. Should be pretty easy
with SRV records but my experimental BIND server does not deliver the
expected result. Also i am not sure if these records are implemented
in IE7 or Firefox.
Aslo any suggestions on how to support multiple grographically dispersed web
servers are welcome.

Here is the zone file:

$TTL 86400

@       IN      SOA     ns1.cska.dom.      dnsadmin.cska.dom. (
                      5        ; serial number YYMMDDNN
                       28800           ; Refresh
                       7200            ; Retry
                       864000          ; Expire
                       86400           ; Min TTL
                       )
