Not much they can say really. If the problem is with Level3, TATA, Cogent, TiNet, or Verizon--SE doesn't have any dealings with them. That is your ISP negotiating with them for routing to Ormuco.
Need to get your route(s) specifically to the FFXIV servers looked at. Just for an example, here is a trace to the server I am currently signed into for Midgard:

My ISP is directly responsivle for hops 2-8, when I get handed of to one of their routing partners (in this case, TATA). Then TATA takes over to get me to their exchange at hop 14 that puts me on Ormuco (SE's ISP). From there, SE has direct influence for resolving issues.
Prior to that 15th hop--my ISP is the best candidate for resolving any issues along my route. If it is between 2-8, they can address it directly, as it is on their network. If it is between 8 and 15, it is an issue for their routing partner--they can either work with TATA to get it resolved, or they can alter my route to use a different routing partner--there are 4 more that peer directly with Ormuco, and TWC has arrangements with at least two of them because I've been put on them repeatedly when I have problems.
***I should note here that I frequently get changed amongst TATA, Cogent, and Level3 because we have been tracking issues tied into these third party ISP's they are using to get me to Ormuco. It changes up about every 3 weeks on average, but sometimes it may change twice in one week, depending on how bad we see things get. My ISP is making these changes and not SE, as I have been in contact with TWC-SC's Tier3 techs in the past and they have been monitoring things more closely since.
We see the culprit being issues between these third party exchanges the vast majority of the time. So you really should get your route(s) looked at.
