One or more users running on Amazon Web Services accounts have been sending a steady and unsustainable stream of requests to SkyView, overloading the servers and severely degrading SkyView performance for others. We’ve temporarily blocked some SkyView access from any Amazon AWS doamin. We expect that this issue not an intentional attack so we have tried to limit the impact and will remove the block in few days.
Generally speaking we advise users to queue their requests, only submitting the next request when the previous one finishes. While one can gain a bit with two queues anything more than that can certainly affect overall SkyView performance. Alas, this is a pretty small site with just a couple of machines underlying everything.
Our apologies to those who have been affected.
