good bye FFXIV, thanks to the lag, you lost another customer.

Sorry, but considering there are basically no other games with issues this big it is not solely the ISPs.

Since other games aren't hosted on the same servers I'm not quite sure what the performance of other games has to do with the issue at hand. One game or service working while another doesn't isn't real proof of server problems because that's not how internet trafficking works.

There could be a number of reasons why you lag in a game, which admittedly includes problems with the server itself. However, the most common issues are typically caused by your ISP or bad routing. It's rarely the actual game servers themselves, as much as they make an easy scapegoat. Actual server problems are generally widespread and affect lots of people at once (see: the threads that crop up when the servers crash). Isolated problems like what the OP describes usually points to an ISP or something in between that a company like SE has no real control over.
