You still didn't figured out by yourself?
Ok, let me break that for you.
Wupload is sister company of Filesonic.
All uploaders, once they felt dropdown in earnings, because there is no rebill option at Filesonic, were 'forced' to move to another filehost, and take their uploads with them. And natural choice was Wupload. Same, and even better conditions at the beginning, attracted 99% of Filesonic uploaders. And not just Filesonic...
Well, since Filesonic have about 5X more servers, Wupload can't cope with remote uploads, and all other type of uploads, with that small amount of servers.
That is why you see Willy replying they are getting new servers.
30 minutes waiting time isn't introduced to cut off your earnings. (Well it is what it directly does) It is there to slow down amount of requests, that they are getting from free downloaders. Well, servers get enormous amounts of hits from both sides, way too many uploaders, and downloaders at the same time.
So, 30 min. isn't a 'test', it's the effort to try to make less hits from free downloaders, and save some bandwidth for those who payed for premiums, and uploaders. However, amount of servers they have isn't enough to cope with all the traffic.
So, you are getting less downloads, because of bigger waiting time, and much slower speeds.
They simply didn't calculated good, how many servers they would need, and never took in their calculations, that, boom they could get, would be literally bigger than Filesonic had. Now, they screwed everything.. :S
Not sure that new servers would do any good, because they would have to have more servers than Filesonic have now....
Also, it's been more than 30 days that uploading speeds are miserable, so, to provide new content faster on wupload, than any other filehost, is literally impossible. Everything shows up on other filehosts much faster, and while you upload to wupload, downloaders are already sleeping, with jdownloader turned on....
And ofc he won't tell you they screwed in calculations. Well, actually, he does, by saying they are getting new servers...
Also, uploading from USA isn't a routing issue. Filesonic is also in EvoSwitch DC, and they don't have any routing issues. And also, that could be easily seen with zooms uploader, which starts to upload with 5-6MB/s, and when another uploader gets the same server, speeds go down drastically. Nothing to do with routing.
Hope this makes things more clear
