[clamav-users] TTL on the current.cvd.clamav.net TXT resource record.
The ClamAV Virus Databases FAQ (http://www.clamav.net/lang/en/faq/faq-cvd/) says: You can check for database update as often as 4 times per hour provided that you have the following options in freshclam.conf: DNSDatabaseInfo current.cvd.clamav.net DatabaseMirror db.XY.clamav.net DatabaseMirror database.clamav.net Replace XY with your country code. If you don't have that option, then you must stick with 1 check per hour. But the TTL (Time To Live) on the current.cvd.clamav.net TXT Resource Record is 10800 seconds (3 hours). ~$ dig @ns3.clamav.net txt current.cvd.clamav.net [...] ;; ANSWER SECTION: current.cvd.clamav.net. 10800 IN TXT 0.97.6:54:16685:1360928385:0:63:40236:214 [...] This will cause the record to be kept in DNS caches for 3 hours and it will reduce the effective update frequency to once in 3 hours (unless you can flush your resolver casches). Shouldn't the TTL be reduceced to something like 900 seconds?

Re: [clamav-users] TTL on the current.cvd.clamav.net TXT resource record.
We temporarily bumped the TTL up to three hours yesterday to ease the burden on the mirrors while we pushed out a change that would cause a lot of bandwidth. The TTL will be set back to its previous value soon.
