Restart bind after updating zonefile billy crudup dating now
In the hosting industry, the Domain Name System (DNS) is one of the most critical pieces, right behind websites themselves.Without DNS, that website you've worked so hard on would be completely invisible.Perhaps it was too busy handling other requests just then.The Retry Interval simply tells the secondary name server to wait for a period of time before trying again.Unless you are manually editing the zone files (something that is not uncommon when using BIND), most DNS servers or frontend DNS applications will increment the serial number for you.But if you find that updates are not being propagated to the secondary name servers, the serial number is the first thing you should check.If you control the secondary name servers and the zone file doesn't change that often, then you might want to set this to as long as day (86400 seconds), especially if you can force an update on the secondary name servers if needed.But if your secondary name servers are not under your control, then you'll probably want to set this to somewhere between 30 minutes (1800 seconds) and 2 hours (7200 seconds) to ensure any changes you make are propagated in a timely fashion.
Without a working DNS record, virtual websites are completely inaccessible.) But I've found that DNS is something that is not well understood by many website operators.A good retry value would be between 10 minutes (600 seconds) and 1 hour (3600 seconds), depending on the length of the Refresh Interval.Time in seconds that a secondary name server will treat its zone file as valid when the primary name server cannot be contacted.Any change requires time before it will be seen everywhere on the Internet.But what many don't understand is that how fast or slow these updates are propagated is actually under their direct control through the SOA record. Although you have control over the speed that updates are propagated throughtout the Internet, they will never, ever, be instantenous! Your only control is over how short or long this delay will be.
