A couple of weeks ago, I was lucky enough to accompany several of my colleagues to O’Reilly’s Velocity Europe conference, which this year was held in Amsterdam.
Velocity isn’t just about making the web faster – it’s also about efficient, effective devops practices. But although web performance is just one aspect of Velocity, it has still been the place to go if you’re interested in building faster websites.
Late on Wednesday 16 November, we noticed something quite strange. Server errors were being returned for objects on a large number of our monitoring customers’ websites. The problem was short-lived but widespread enough for us to investigate.
Is your website meeting KPIs for speed and availability? Are key user journeys working as they should? Is your website’s performance now the same as it was this time yesterday? Are you sure? How can you tell?
