We have been able to identify the sending issues and expect normal email deliverability for customers using shared email hosting to be restored over the next 24-48h.
Customers using custom domains should be able to deliver emails immediately.
Customers using HTTP passthrough subdomains for web push are unable to subscribe new subscriptions, however existing subscriptions will continue to receive notifications. This will resolve over the next 24-48h.
Most OneSignal customers do not currently use these features and are not affected.
