TLDR: If Calendly isn’t loading or booking, check the official status page and apistatuscheck.com/down/calendly. Most issues are caused by calendar integration failures, rate limits, or availability rules—not a full outage.

Is Calendly Down? How to Check and What to Do

Calendly is the backbone of scheduling for sales teams, recruiters, and support orgs. When it fails, meetings don’t book, confirmations don’t send, and pipelines stall. The key is knowing whether you’re seeing a global outage or a local scheduling or integration issue.

This guide walks you through confirming outages, understanding common errors, and keeping your scheduling running if Calendly is down.

How to Check if Calendly Is Actually Down

Step 1: Check the Official Status Page

Official status: status.calendly.com

Calendly’s status page reports incidents across:

• Web app
• Scheduling pages
• API
• Integrations
• Email delivery

If you see degraded performance for the Scheduling Pages or API, that’s a strong signal the issue is on Calendly’s side.

Step 2: Check Independent Monitoring

Independent checks help confirm whether the issue is global or specific to your environment.

Step 3: Test a Known-Good Scheduling Link

Try a public scheduling link from another team member or a sample link from a different account. If those work, the issue may be:

• A specific event type
• A calendar integration
• Availability or routing rules

Step 4: Test on a Different Network

Switch networks or devices to rule out local DNS, VPN, or browser cache issues.

Common Calendly Error Messages (and What They Mean)

“Scheduling Page Not Found” (404)

Meaning: The booking link is invalid, deleted, or private. What to do: Confirm the event type still exists and the URL is correct.

“Something Went Wrong” (500/502)

Meaning: Server-side error while loading the page or creating an invitee. What to do: Retry after a few minutes and check the status page.

“Too Many Requests” (429)

Meaning: You hit API rate limits or a burst of traffic. What to do: Reduce request volume and implement backoff for API calls.

“Calendar Connection Error”

Meaning: Google or Microsoft calendar integration is disconnected or expired. What to do: Reconnect the calendar and reauthorize access.

“No Times Available”

Meaning: Availability rules, buffers, or busy calendars block all times. What to do: Review availability, buffer settings, and connected calendars.

“Webhook Delivery Failed”

Meaning: Your endpoint is rejecting or timing out on Calendly webhooks. What to do: Check your webhook endpoint, verify TLS, and retry failed deliveries.

Troubleshooting Steps Before You Assume an Outage

1. Check availability rules

   • Verify event type hours, buffers, and minimum notice.

2. Confirm calendar integrations

   • Ensure Google/Microsoft calendars are connected and authorized.

3. Test a different event type

   • A single event type can be misconfigured.

4. Clear browser cache

   • Cached scheduling pages can break after updates.

5. Test in incognito

   • Rules out extension conflicts.

6. Check invitee time zones

   • Time zone mismatches can hide available slots.

7. Validate API keys

   • If using the API, confirm the token is current and scoped properly.

8. Review security settings

   • SSO, SCIM, or domain restrictions can block access unexpectedly.

If Calendly Is Down: What to Do Next

Communicate Quickly

If scheduling is critical, notify your team and clients:

• Post a brief note on your status page or email
• Provide alternate booking options
• Offer manual scheduling as a fallback

Use Temporary Alternatives

Here are reliable fallback tools:

• Google Calendar Appointment Schedules – quick built-in scheduling
• Microsoft Bookings – great for Microsoft 365 orgs
• Acuity Scheduling – strong for client bookings
• SimplyBook.me – easy setup, good for teams
• Doodle – fastest for finding a consensus time

Manual Scheduling Playbook

If you must schedule manually during downtime:

• Use a shared calendar
• Offer 2–3 time windows via email
• Send a calendar invite directly once confirmed

Preventive Best Practices

Set Up Redundant Booking Links

Maintain a backup booking link on a secondary tool so you can switch quickly.

Monitor Calendar Sync Health

Integration failures are the #1 source of “Calendly is down” reports. Set reminders to check your connected calendars monthly.

Rate Limit API Workflows

If you generate or update events programmatically, implement backoff and retries to avoid 429 errors during traffic spikes.

Keep Availability Rules Simple

Complex buffers, multiple calendars, and routing forms increase the chance of no-availability errors.

Quick Checklist

• Check status.calendly.com
• Verify apistatuscheck.com/down/calendly
• Test another scheduling link
• Reconnect calendars
