Latest update from PostHog
Status: Monitoring We identified the customers that have been affected by the incident and of which their workflow email sending workflow steps show as failed and stopped the workflow run. The emails for the failed steps went out, but the workflow aborted at that point. We are working on resuming the failed workflows and will inform the affected customers.
What our independent monitoring saw
Our checks of PostHog's public login and customer-facing pages kept responding during this incident, so the problem was most likely inside the product (for example a specific feature, region or integration) rather than a full site outage.
Other outages around the same time
Significant incidents other vendors reported within 12 hours of this one.
