If these changes were just made recently, you might have to wait up to 48 hours for the DNS changes to propagate. Why you are using a TTL of 8 seconds short of a day, I don't know. If you have the IP address of the ISP's DNS servers, you may be able to query directly to their servers to see whether it is a DNS resolution error at all... Whether you really want to be using CNAMES in the first place, or whether you want to be using a different top level domain (TLD) as the RR of the CNAME is a completely different question. What you are doing /should/ work fine, but is going to generate marginally more DNS traffic than is strictly required. It would be faster and more efficient (DNS-wise) to have each name be a full A record pointing to the same address as loadbal.asylumweb.net.
