Stripe has resolved the incident (https://status.stripe.com/), and from our side we haven't seen any further errors for around 20 minutes, so we're closing this from our side too now. Have a great weekend!
On the Skedda side, payment-related requests (e.g. creating a booking that involves online payments) may fail with an error message. We invite you to refer to Stripe's status page linked above for tracking this incident. We'll post updates here as required and resolve the incident when Stripe does.
