One thing we’ve always known: there’s no such thing as 100% uptime for any website. Too many variables are at play to keep a site from staying up all the time. From traffic surges to hardware failures and everything in between, keeping sites up and running is a full-time job for SREs and IT pros. Here at Uptime.com, we track major downtime all year long to provide websites of all sizes with lessons in how to catch downtime and resolve incidents quickly.

Tis’ the season for website downtime. No matter how great your web infrastructure is, many ecommerce sites experience downtime on Black Friday. You’re not alone. New research by Google Cloud says that one out of ten retail executives reported downtime on Black Friday 2018, and four out of ten reported outages during one of the past three years.
