Response time data is useless without other data: - Where are the monitors located? - Where are the sites located? - How was the site monitored? Did they account for DNS lookup and connection times in this time? 8ms for skysheet.com makes me think no? - Are error times rolled into these times? Errors typically will respond quickly. Having built www.yottaa.com, we worked hard to provide data that users can easily take…
- All monitoring is from EC2's us-east-1 region.
- I don't track the location of the sites, other than specifying the vendor.
- Data is generated by an open source tool called Stella. I'm not currently tracking DNS lookups but probably will eventually.
- Tests with errors are not included in the response times.
The specific response time is less interesting than looking at how a site performs over time (the number and duration of downtime, errors, etc). There are a lot of rabbit holes in testing so what I'm focusing on now is the simplest possible solution that works.
