As DOSarrest expanded its DDoS protection cloud, now located in London, UK, NYC, LA, Vancouver, Hong Kong and Singapore, we needed to know the uptime and performance of all of our customers' sites as viewed from all 6 locations. We set out to find an external 3rd party service that we could subscribe to in order to fulfill this requirement. What we had hoped and thought to be a fairly straightforward exercise and at a reasonable expense was not. After months of searching we soon realized that it was going to cost from $200.00-$400.00/month per URL to accomplish our goal. This added cost was obviously not going to be feasible, given the hundreds of domains presently under protection. Plan "B" was put in motion, which was the development and deployment of DOSarrest External Monitoring Service(DEMS).
After almost 2 years of development and testing the result is one of the best distributed monitoring systems available today at a reasonable price.
If you're using a CDN to distribute your website on a global basis things may appear fine when viewing your website from your vantage point, but the website could be completely unavailable in another part of the globe. Would you know if it's down? Would you know real-time if it's very slow? Sales dropped off yesterday in Asia, can you go back and see what happened closer to where the sales drop was?
You are a Managed Hosting provider servicing 50 mission critical websites.
A call comes in with a complaint from a customer saying, "I'm in Florida and my site is down!" Could you tell with one glance, that the site is in fact up and it is this particular viewer that has an issue and not the website? Or will you spend a couple of hours trying to figure out what and where the problem is?
DEMS is one of the easiest ways to keep track of tens or hundreds of websites in real-time, a perfect Managed Hosting tool.
The system is comprised of 8 sensors located in 4 different geographic regions. Each sensor is located externally to any of DOSarrest's networks' and performs the following checks every 60 seconds:
All of the above data is collected and archived and available for real-time auto-refreshing views or historical viewing.
See how easy and intuitive DEMS can make the real-time monitoring of all of your websites from multiple locations actually be!
