Mine got better after the fix but today it has just got longer and longer, several minutes at the moment
Well it was happening to me long time ago , it happening to me today again, it was happening in random order, like one hour terrible delay when jumping out of hyperspace. Often it happens when client is ordered to communicate with different instance than it is current one, and often that is case when u jumping. Delay happen just bec. you can not establish connection to another server/instance when exiting from hyperjump. Why it happen now and than but not constantly , nor every day , do not know, probably it have some connection with how busy servers are. Or you jump in to empty system with no players in SC , than you have to create new instance for yourself only when exiting hyperspace and it fails , fails, fails and so on till it success. That is your delay. All such delay have more connection to quality of your connection to the internet than with ED servers. You know it is p2p game , so you just informing ED server about new instance you created or asking server about what instance you goin to join when exiting Hyper Jump. If connection with server can not happen , or it is bad or it fails for some time till success , you getting delay. If it fails totally you going to be disconnected. I got all above from my own problems , but I use different Internet service providers from more than few location , and the worst one is this one from where I typing this. Often here a lot of delays when exiting from jump, and causally disconnected from time to time. While at my home, different ISP and almost never delays. At my weekend house 3rd ISP which sometimes yes getting delays , sometimes yes for disconnect but majority of time it working good.
My conclusion is most of time it happening because of your connection even when you think it working perfectly with other services it can be problematic when it comes to work with ED servers.
But still there is high possibilities that is can happen bec. ED servers are to busy.
