That"s why the new method of using DNS to cache the version number will be a much better solution and I think it will allow more frequent checks without burdening the mirrors and shifting the load to the DNS infrastructure.
I am not a DNS expert by any means and I may be way off in left field here but you may want consider that there are many a server behind gateway appliances or proxies that cache DNS for a fixed length of time. I really have no idea if there are devices that do not obey refresh values but the bigger question is: do you?
There are....
Without knowing for sure how these devices handle the DNS refresh I would be cautious. It may not be an issue if the server were configured to use a real a DNS server to obtain records, but I would think many internal servers are configured to obtain records from gateway proxies/routers/appliances and if configured to do so, and these devices do not obey rules, the records they see may be 12 hours old or older.
Just something to consider. I could be wrong.
You can choose the DNS server you want to use for your virus scanner, can't you?
DNS is definitely the method of choice to distribute such information. It has been designed for fast distribution of small information chunks, and TTL has been there forever, so any implementation not respecting these values should be scheduled for deletion anyway.
