Since checking the DNS TXT record costs almost nothing (and is UDP), I figure I can do it more often than running freshclam without ever risking triggering Cloudflare's bandwidth limits. And, although I currently do it only once per hour, if there ever was something like a SANS Threat Level RED, I could up the frequency to get the latest sigs ASAP.
