Uptrue's independent monitoring tracked American Express and Chime throughout the week of 20 April 2026. American Express maintained 100% uptime with a 90ms average response time, while Chime recorded 0% uptime during the same period, indicating a complete service outage.
- American Express: 100% uptime, 90ms response time, zero incidents
- Chime: 0% uptime throughout monitoring period
- Response time data unavailable for Chime due to service unavailability
- Zero recorded incidents for both providers despite significant disparity in availability
Uptime This Week
American Express delivered perfect availability at 100% uptime during the monitoring week. Chime experienced a complete service failure, registering 0% uptime. This represents a critical reliability gap between the two providers during this measurement period.
Response Time
American Express averaged 90ms response time, indicating healthy application performance. Response time data for Chime was unavailable due to the total service outage preventing meaningful measurement.
Incidents & Downtime
Neither provider recorded formal incident events in Uptrue's monitoring system despite Chime's total unavailability. This suggests the outage may have been underlying infrastructure failure rather than discrete, tracked incidents. The lack of incident logging does not indicate service reliability—Chime's 0% uptime clearly demonstrates extended service degradation.
Which Should You Choose?
American Express is the clear choice for reliability-critical applications requiring consistent uptime. Organizations currently dependent on Chime should investigate the cause of the outage and establish contingency plans or redundancy measures. If this represents a recurring pattern rather than isolated failure, alternative providers warrant evaluation.
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
