Yup, I'm seeing the same thing, pings went from 59ms to 109ms. Yet another example of NTT's terrible service outside of Japan. I really feel like I'm shouting in to the void here since none of these threads are ever even acknowledged by SE, not even a "We are aware of this issue and are working with NTT to resolve", nope just crickets. The issue will silently go away some time in the next day or two (hopefully) and then all this will repeat again in a few weeks/months.
