Somebody is launching a shitload of XT nodes all on VPS hosting, the next step in the saga.
What makes you believe it is one person? What makes you believe they are using VPS hosting?
Could it not be people waiting till the weekend to have the time to make the switch?
right 2 weeks after its taken 75% of HASHING power not number of nodes
its currently at 0.3% of hashing power ( up 300% from yesterday )
it might be hard for XT to get 75% miners seem to prefer the idea that 1MB limit will soon bring in higher TX fees

from xtnodes.com if you hover over image at top right corner "The light will become green and say YES once 750 of the past 1000 mined blocks (75%) first reach support of BIP 101 (and Bitcoin XT). From that point, 2 additional weeks must pass until the maximum blocksize is raised to 8MB. It must also be Jan 11, 2016 or later to go into effect.
