HTC EVO 4G owners trying to use Qik Video over the weekend found themselves running into all sorts of connection issues thanks to overwhelming and unprecedented demand.  The Qik blog is telling us that they have had to temporarily unpublish the video calling application over extreme workloads.  Qik is reporting that their servers were hit with twenty times their normal requests.  The company is working to provision more capacity and hopes to have things back up before long.
