23 Facts on GitHub Reliability in 2022: Data Study of Outages by StatusGator

With over 83 million users, GitHub is one of the most popular development tools out there and the third most monitored service on StatusGator. 

Since so many users depend on GitHub, we wanted to analyze GitHub’s reliability in 2022 and find and uncover some interesting facts about GitHub outages. 

The data behind this article

For our analysis of GitHub’s reliability, we used historical outage data for GitHub. The data comes from our own product, StatusGator, which aggregates data from official status pages to create team status pages. 

GitHub’s status page identifies two severity levels for each downtime event. These are degraded performance (marked in yellow) and degraded availability (marked in red). For clarity, this article refers to degraded performance events as minor incidents and degraded availability events as major outages.

In this article, we presented 23 facts on GitHub reliability in 2022. 

Our data was unique, and we found some useful facts. However, we must admit that GitHub is reliable

This is because all features rarely go down at the same time, and since it is such a commonly used service, this is beneficial for GitHub’s reliability. 

We do, however, see two points that require improvement:

  1. Codespaces is obviously less reliable than the other features. If this could be improved, GitHub outage and incident data could be seen to improve. 
  2. The communication for outages and incidents doesn’t contain any information about the reasons why they happened. We’re not saying GitHub isn’t transparent, but it would be hugely beneficial if this was improved in the future.
