Duplicate payments, slow confirmations

Hey there,

Unsure what changed from yesterday to today, but processing delay between checking out with woocommerce, payment processing and positive result has increased to 30 seconds with no indication of why or that it is in fact working. Customers then hammer on the purchase button several times and duplicate purchased for identical posts are processed. This began 24 hours ago and I can’t seem to figure out why. Please help!
