How To Monitor Voice Connectivity – Inbound Line & SIP Monitoring

Voice Connectivity is Critical. Your phone systems have gone down and you are unable to communicate with your customers. After several hours of troubleshooting you have managed to get the services up again but what do you do now?

New Features to Test How DNS Caching Affects Your Website

The new DNS caching features at Dotcom-Monitor allow you to perform some interesting tests that show how DNS caching can affect your page load speed.

We realize that many organizations monitor their online services with a number different goals in mind, and so we listened to the feedback we received that some users want to include the DNS response time in their monitoring and some users want to be able to remove DNS response from their monitors.

How you wish to handle DNS response time in regard to your monitoring needs is up to you, but we want to take this opportunity to show the differences in how DNS response time affects website load using our new tools.

We ran a test monitoring YouTube from a single location in the midwest United States with three different DNS cache settings. A basic HTTP full page load on the YouTube front page resulted in some interesting, although not that surprising results.

Keep in mind the results will vary depending upon a number of variables such as which locations you are monitoring from, the time of day, the load on the DNS servers, and on the website servers.

The problem of not knowing for hours that your site has appeared on a DNS Blacklist (DNSBL) and that email—and, even worse, potentially website visitors—are being rejected is a problem with both primary impacts and multiple secondary impacts.

Innovations in Microsoft Exchange Monitoring

Microsoft Exchange continues to grow in popularity, but until recently active monitoring via full round-trip processes have been lacking in the marketplace. As a result network administrators have found it difficult to accurately pinpoint Microsoft Exchange issues effectively. Dotcom-Monitor’s Microsoft Exchange Monitoring, actively monitors both the availability and performance of Exchange components and provides alerts and diagnostics information when an issue is detected. Among a wealth of other features, the solution includes the industry’s only tool for monitoring ActiveSync externally, so it mimics the same experience a real user would receive.

Five Tips to Help Your Mobile Website Meet User Expectations
