Hi Ant I'd understand that to mean basically that, although the package was at the UPS facility, it did not go out for delivery with all of the other packages that were there at the same time (or that were scheduled for delivery on the same date) for some reason. The package will therefore be delivered one (business) day later than originally expected. If the package was originally scheduled for delivery on a Friday, "the next business day" will probably be the following Monday.
