It could be for reasons beyond their control. Last week, Wednesday maybe, the entire Oracle download site was unavailable. It turns out that a new Java virus had been generated by another set of deviants who want to foul up your life just for giggles. It sometimes takes a few days for some Internet service providers (ISPs) to put the fixes in place on their equipment, preferably on weekends to minimize business disturbance. This normal practice is to not tell the public, else they will lose customer confidence and customer revenue.
Just ride this minor annoyance out.....
