DNS Monitoring Improves Web Site Speed and Reliability – Part 2
Dotcom-Monitor uses a non-cache DNS monitoring solution with high frequency monitoring that propagates DNS queries to the root name servers. That means a DNS issue will be identified quickly, as opposed to being masked for days as it might be with a cached monitoring approach. When monitored properly, using a non-cache method, an error is quickly identified so the designated workaround, like a DNS failover, can be implemented.
Dotcom-Monitor non-cached DNS monitoring (unlike some other cache-based DNS monitoring solutions) also provides diagnostics with an automated trace-route as soon as a DNS problem is detected. This means less time investigating the problem and much faster mean-time-to-repair (MTTR). The Dotcom-Monitor DNS monitoring solution also allows website owners to spot trends so that small DNS issues can be addressed before they become big DNS problems.
