www.paypal.com was unavailable to most customers for more than an hour today, with no estimated time for resolution during the outage. PayPal uses scheduled maintenance windows every Thursday and Friday from 11pm to 1am PST, but this rarely results in any noticeable downtime, and today's outage extended beyond that window.
PayPal's payments API was also unavailable, which will have affected many online retailers, including PayPal's owner, eBay. A statement from eBay at 12:52am PST said: "EBay [sic] is currently experiencing checkout problems. Community members may see errors or timeouts when attempting to pay for an item. We are working on the problem and apologize for the inconvenience."
A live status update on the PayPal X Developer Network stated that there was no alternative work-around to the problem:
The problems with the PayPal website and payment APIs were resolved at 1:23am.
