We are happy to announce some wide-ranging improvements to our status page. While it looks the same on the surface, it has been rewritten from scratch and is now much more tightly integrated with our monitoring infrastructure. For our customers, this has three main consequences.
Fully automated status updates
Status changes are now fully automated. Over the last few months we have carefully tuned the sensitivity of the status page to the point where we are now happy with its accuracy and responsiveness. While we continue to improve the algorithms that monitor our infrastructure, the status page reflects the health of our infrastructure better than ever.
Better differentiated status
We now differentiate between increased latency and reachability for the status of the proxies in our clusters. For convenience we use a simple traffic light approach: green means all proxies in a cluster are up and running and responding quickly enough, yellow means one or more proxies in a cluster are responding more slowly than usual, and red means that our monitoring infrastructure is unable to reach the proxy at all.
Previous support incidents have revealed that customers often visit our status page after an incident has already been resolved. They are then puzzled because all our clusters show green statuses when they have clearly just had trouble connecting to our servers. To avoid this confusion, we now flag such clusters as “Recently Resolved” and highlight them with the color blue.
All these changes are also reflected in the status RSS feed. Please let us know if you think these changes are useful or what other features you would like to see next. We have an ongoing program of improvements in system monitoring and fault diagnosis, but we’re always very happy to hear ideas from customers that would make their experience using MemCachier better!
