Monitoring - We're continuing to monitor email deliverability to Yahoo-based addresses. While some messages are now being delivered successfully, intermittent failures are still occurring.

We're actively working with our email provider to confirm full recovery and understand the remaining delays. These types of issues can take some time to fully stabilize, which is consistent with similar situations we've seen in the past.

We'll continue to monitor closely and will share another update in the morning. Thank you for your understanding while we get this fully resolved.

Cloudflare Outage — Teachable Traffic Disruption (2025-12-05 04:50–05:10 ET)
Resolved - Incident Summary
Between 4:50am and 5:10am ET, Teachable experienced a brief period of unavailability. During this time, some visitors were unable to access teachable.com and related domains.

What Happened
A widespread outage at our upstream network provider, Cloudflare, temporarily disrupted traffic to Teachable. Because we route traffic through Cloudflare for security and performance, their outage prevented requests from reaching our platform.

Impact
Users may have encountered errors or been unable to load Teachable during the 20-minute window.

Resolution
Cloudflare resolved the issue, and access to Teachable was fully restored. No action was required from users, and all systems have remained stable since.
