Just wanted to provide a link to the official thread on this issue:
http://forum.square-enix.com/ffxiv/t...Data-Center%29
And to Ariellandra... this is kind of a longstanding issue, it still surfaces on the FFXIV Reddit from time to time but people mostly just go "Oh it's that one NTT node." I don't know if there's anything you could do to pass things up the chain and get more done about it. I'm sure people both here and on reddit would happily collect data and pass it on if SE asked again, as in the linked thread.
Here's an example of what I mean:

WinMTR v0.92 GPL V2
The specifically problematic node in my case is ae-12.r22.snjsca04.us.bb.gin.ntt.net, which here has 63% packet loss in the morning, probably much worse in the evening.
In the evenings/busiest hours, this can manifest with symptoms identical to what MeowTo described, though most evenings I'm fortunate in that I don't have issues. Or it can simply 90k (the error code, 90003) me out of an instance when all appeared to be fine.
On reddit recently, there was even a post showing this happening at PAX: https://www.reddit.com/r/ffxiv/comme...iv_experience/
