Incidents & Downtime

Atlassian recorded zero incidents and zero minutes of downtime during the monitoring week. GitHub experienced two separate incidents resulting in 19 minutes of cumulative downtime. The frequency and impact of these interruptions may affect teams with strict SLA requirements or critical deployment schedules.

Historical Context

Dev tools and CI/CD platforms have become increasingly resilient over time, with most mature providers targeting 99.9%+ uptime. However, even minor incidents in these services can cascade across development pipelines, making incident frequency as important as overall uptime percentages.

Which Should You Choose?

Choose Atlassian for maximum reliability when incident-free operation is paramount, particularly for teams with zero-tolerance deployment windows. Opt for GitHub if response time and performance are priorities and occasional brief interruptions are acceptable. Most teams benefit from monitoring both platforms independently rather than relying on a single provider.
