  • Calendly responded 5x faster, averaging 147ms compared to Fibery's 730ms
  • Neither provider experienced any downtime events requiring incident response
  • Response time variance suggests different infrastructure or regional serving strategies between the two platforms

Uptime This Week

Calendly 100.00% Fibery 100.00% HTTP checks every 5 min · 7-day period · Uptrue independent monitoring

Both providers demonstrated flawless availability during the monitoring period, each maintaining 100% uptime with zero recorded incidents. This equal performance reflects robust infrastructure on both sides, though it does not differentiate their reliability profiles during this specific week.

Response Time

Calendly 147ms Fibery 730ms Lower is better · Median TTFB · Excludes model inference time

Calendly's average response time of 147ms substantially outpaced Fibery's 730ms—a 483ms gap that directly impacts user experience, particularly for calendar lookups and scheduling interactions. This five-fold difference suggests Fibery may be serving globally distributed requests or using heavier application logic per request.

Incidents & Downtime

Calendly No incidents Fibery No incidents Incident = 2+ consecutive failed checks · 7-day window

Neither provider recorded any incidents or downtime during the monitoring period. Both maintained continuous service availability, indicating stable production environments and effective incident prevention practices across their respective infrastructure.

Historical Context
Collaboration and scheduling tools have become increasingly critical to business operations, making consistent uptime a table-stakes requirement rather than a competitive advantage. Performance differentiation through response time has grown more important as teams rely on real-time synchronization.

Which Should You Choose?

Choose Calendly if response speed is a priority for your scheduling workflows, particularly in latency-sensitive environments. Select Fibery if feature depth and collaborative document capabilities outweigh the response time trade-off, or if your use case tolerates higher latency.

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 based on this data?
Both Calendly and Fibery achieved 100% uptime during this monitoring week with zero incidents, making them equally reliable during this period. Reliability cannot be determined from a single week of data; longer-term monitoring patterns are needed to establish differentiation.
How often does Fibery experience downtime?
During the week of April 20, 2026, Fibery recorded zero downtime events. Uptrue's independent monitoring showed continuous availability, though reliability assessment requires observation across multiple weeks or months.
How is this reliability data collected?
Uptrue independently monitors both providers' availability and performance by making regular synthetic requests to their production endpoints. This data comes directly from Uptrue's monitoring infrastructure, not from the providers' own status pages or internal metrics.
