⚙️ Dev Tools & CI/CD Weekly Comparison

Atlassian and CircleCI both serve critical roles in development workflows, yet they demonstrate notably different reliability profiles. According to Uptrue's independent monitoring during the week of 20 April 2026, Atlassian maintained 100% uptime while CircleCI achieved 99.75%, a gap driven by a single 10-minute incident.

TL;DR

Atlassian delivered perfect 100% uptime with zero incidents; CircleCI recorded 99.75% uptime with one 10-minute outage
CircleCI's response time averaged 92ms, substantially faster than Atlassian's 174ms
Atlassian experienced no downtime events during the monitoring period
CircleCI's single incident represents the only service disruption across both providers this week

Uptime This Week

Atlassian achieved 100% uptime across the monitored period with zero recorded incidents. CircleCI's 99.75% uptime reflects one 10-minute service disruption, which translates to approximately 1 hour 26 minutes of potential downtime per month if extrapolated. The 0.25% gap is marginal in absolute terms but represents the measurable difference in availability during this monitoring window.

Response Time

CircleCI demonstrated significantly faster response times, averaging 92ms compared to Atlassian's 174ms—an 89ms advantage. Both response profiles remain acceptable for CI/CD workflows, though CircleCI's faster median latency may reduce friction in rapid deployment cycles. Atlassian's response times remain well within operational tolerances for repository and project management tasks.

Incidents & Downtime

Atlassian recorded no incidents or downtime during the monitoring period. CircleCI experienced one incident resulting in 10 minutes of total downtime. This single event represents CircleCI's reliability event for the week and accounts for the measurable difference in reported uptime percentages.

Historical Context

Dev Tools and CI/CD platforms typically maintain uptime in the 99.5–99.99% range, as build systems and deployment infrastructure must balance feature velocity with stability. Providers in this category have increasingly emphasized incident transparency and rapid recovery procedures.

Which Should You Choose?

Choose Atlassian if zero-downtime guarantees and proven stability are non-negotiable for your deployment pipeline. Select CircleCI if faster response times and reduced latency in build execution offset the minor availability gap, particularly for teams running high-frequency deployments. Both providers demonstrate strong reliability; the choice depends on whether you prioritize absolute availability or response performance.

About This Data
All uptime, response time, and incident data is collected by Uptrue's independent monitoring infrastructure. HTTP checks run every 5 minutes. An incident is recorded only after 2+ consecutive failed checks. Uptrue is not affiliated with any monitored service. For corrections: reports@uptrue.io

Frequently Asked Questions

Which provider is more reliable?

Atlassian is more reliable based on this monitoring period: 100% uptime and zero incidents versus CircleCI's 99.75% uptime and one 10-minute outage. However, the 0.25% difference is small in practical terms; both services demonstrate high reliability for production CI/CD and repository management.

How often does CircleCI experience downtime?

During the week of 20 April 2026, CircleCI experienced one incident resulting in 10 minutes of downtime. This represents a single outage event during the monitored period. If this pattern were to repeat monthly, it would approximate 1 hour 26 minutes of cumulative downtime.

How is this data collected?

All monitoring data comes from Uptrue's independent uptime monitoring service, which continuously tracks availability and response times across both providers. Uptrue performs external, synthetic monitoring of public endpoints and records all incidents, downtime, and performance metrics without relying on provider-supplied data.
