greenvaluehost 的疑问兼测试
买的 5DAY LET SPECIAL (TX)Node tx1
但是Dallas, Texas的应该是 TierPoint DC的吧，
New York, USA的应该是 ColoCrossing DC的
我看其他人买这个TX位置的IP（206.217.134.116）和我的IP怎么都是 ColoCrossing的？
IP Location: United States United States Olive Branch Shellworld Internet Services
ASN: United States AS36352 AS-COLOCROSSING - ColoCrossing (registered Dec 12, 2005)

看你还是30号买的，我昨天买的200G的，咱们节点也是一样的，
我的账户 vmuser64* 600多个，你的在前面多少个，就能知道他卖了多少了。
