In the last few days, I got the "Twitter is Over Capacity" message probably 5 times. If you are a heavy user of the service, you probably got it too. It has been going for about 2 weeks now.
I'm sorry for the company, but I can understand that, technically, it is quite a challenge to make such a network run smoothly 24/7.
This post is an attempt to show non-technical people what we do, silly billies like me, to allow millions of people to use one single Internet service such as Twitter, all at the same time. The concept is similar for all web based systems: Google, Facebook, Snap! Websites, etc.
