A record high of 162,414 cars per day cross the Golden Gate bridge, in wind, rain, and countless other environmental factors (don’t say earthquakes!) that compound stress on it. An Atlassian instance is a lot like a bridge. Users access each instance hundreds and thousands of times a day, amid conditions that include the size of the instance itself (with its load of comments, pages, repos, etc.), the apps you’ve added, API calls, and much more.
