Note: Outage times display the minimum outage time which may understate each outage by up to 15 minutes, which is the sampling frequency.

Interpreting the Tables
By default the sites are ranked in order of failed requests and time to connect, shortest first, in order to give the clearest indication of network capacity and congestion, with the least impact from the performance of the individual web server, though it is possible to sort by other columns by clicking on the column heading.
Presently our performance collectors are located at New York/New York Internet-2, Italy/Aruba-2, Amsterdam/Webair-2, US West/Azure, Singapore/DigitalOcean and Ireland/Amazon. Sites located near one of our collectors may have an advantage over others listed in the table, though this effect is mitigated by using averages collected from multiple points. Sites exclusively hosted in the Far East are at a disadvantage as we do not currently have a performance collector in the region.
Sites using a Content Distribution Network, such as Akamai, have a particular advantage as the response to our request would come from the node closest to each performance collector.
Using the performance of a hosting provider's own site to determine the performance of the hosting companies network, is only indicative.
If you are using the table as a guide when choosing where to locate a dedicated or collocated server, remember that connection times fluctuate continually, and only hundredths of a second separate the top companies. Avoiding companies showing prolonged outages is likely to be a better strategy than necessarily going for the company with the fastest connection time.
Other factors including availability and quality of support, and price will also be important. If you are considering shared hosting then the load on the shared hosting system will likely be a greater constraint on the performance of your site than network connection time.
