Hi everyone,
Things seem to be back up and running now. Here is the update from Paypal’s site:
We have implemented a fix and IPNs for transactions processed after Jan 28, 10:47 AM PST (Jan 28, 6:47 PM GMT) are being sent now. We are expecting IPNs for new transactions to start being delivered in near real-time within the next hour. We are also estimating that missing IPNs for transactions processed between Jan 27, 11:04 PM PST (Jan 28, 7:04 AM GMT) and Jan 28, 10:47 AM PST (Jan 28, 6:47 PM GMT) will be delivered within the next 24 hours.
As the IPN’s (those are the pingbacks from Paypal to HC) come in, items may be re-taken out of stock. Just keep an eye on your inventory, etc. Hopefully this won’t happen again anytime soon!
Thanks for your patience!
