Always Reachable First and foremost, your customer expects your website to be reachable: 24 hours a day, 7 days a week, 365 and one‐quarter days a year! Reachability and availability are closely related, but different. Reachability means a user can get to your website over the Internet. Routing and DNS are two key components of reach- ability. Availability means your website is actually there (up and running) when a user gets to your web servers! Companies have traditionally focused on availability, which is measured in uptime. Whether or not end users can actually reach their websites from all of their various market regions isn't something most companies have spent a lot of time or effort monitoring and investigating. If end users in a particular large market — for example, Canada — can't reach a compa- ny's websites, it's not necessarily the company's fault ("all of our services are up and running," in other words "available") but the company will suffer the business consequences nonetheless. Always Fast Three seconds can be the difference between a loyal cus- tomer and a lost customer. The majority of consumers don't abandon online shopping sprees because they change their minds or run out of time to make their purchases. Slow‐loading websites and skepticism around security get in the way of completing a purchase for nearly two thirds of consumers globally, according to Dyn's 2015 Report: Global Consumer Online Shopping Expectations. According to this report, two‐thirds of global consumers leave websites at least 25 percent of the time without buying any- thing because they're tired of waiting for the website to load. Retailers and e‐commerce companies lose sales and the potential of life‐long customers because of poor performing websites.
