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.

DNS Monitoring Improves Web Site Speed and Reliability – Part 1

The only way to know how well or how reliably DNS servers perform is to make consistent, regular objective tests and measurements over time. While DNS servers can be verified manually, that is not a practical solution. Manually checking the DNS servers a few times a week, or even a few times a day, simply does not provide enough data to accurately judge performance, nor does it quickly alert website owners to problems. Automatic DNS monitoring gives website owners the information needed.
