In anticipation of the spike in traffic volume today, we upgraded as well as increased the numbers of compute servers, database servers, and load balancers in our backend infrastructure. The additional hardware resources that we put in are capable of handling an estimated 70-100x our typical traffic load. Needless to say it was not nearly enough to handle the demand we were getting earlier today from the Modern Masters drop. While our load balancer and compute servers were able to chug along without any issues, it was our database servers that were the first ones to tap out. Even 5 minutes before the sale started, the amount of requests we were getting was already pushing our database load dangerously close to 100%, and the servers pretty much hovered around 100% CPU load for the following 15 minutes. Thus causing the page to load very slowly. The first order of Modern Masters came in 45 seconds after the drop opened, and 2 minutes later, the last order was placed. Needless to say, these are pretty incredible numbers, of which far exceeded our initial expectation. Our engineering team is already hard at work rolling out a series of optimization improvements and hopefully we will fare much better tomorrow. Thanks for the support guys!
