DO now supports over 1 million users worldwide, growing from a modest start in 2012 with only 4-5 servers and a handful of engineers. The company has expanded to multiple datacenter regions, launched several international datacenters, and partnered with various companies like GitHub and Docker. Developers have played a significant role in helping DO grow by providing feedback and creating tools that extend the API. Many community members have become part of the DO family, contributing articles, engaging with other users, and even joining the DO team. The journey to 1 million users is a testament to the company's commitment to meeting their growing infrastructure needs and collaborating with its users.
