Have you verified there aren't issues along your route to the servers? Not on your end, or your ISP's localized segments (where they usually look when you call in)...but along the path you take to the server--between your location and Ormuco (SE's ISP).

Just saying.. there are lots of problems that can crop up between your local hardware and SE's hardware. Note these images are not static...they will get updated periodically throughout the day. At present, there are a lot of problems being reported--particularly in some hot zones that nearly all of us have to go through to get to the servers in Montreal. These are segments that SE has no influence over, but your ISP should. You can find details on more internet services like Netflix and other ISP's at the parent site here:
