上周五收到一份 DMIT 发送的邮件，DMIT 已经终止与中国联通的合约，以后不提供 4837 线路，目前 DMIT 正在与其他 ISP 服务商接触，以期望取代联通 4837 线路，不过个人认为应该不会有什么结果。因此 DMIT 刚上架没一年的圣何塞 4837 线路要无疾而终了。
因为 DMIT 是搬瓦工 4837 线路的上游，搬瓦工也因为 DMIT 不续签 4837 线路合同受到影响，上线不久的 USCA_FMT8 套餐也更换成直连线路。目前搬瓦工 FMT8 机房只在 THE CHICKEN 和 THE PLAN 限量版套餐可选，没有开放其他套餐的迁移权限。所以目前对于新购买搬瓦工的朋友来说，搬瓦工弗里蒙特 USCA_FMT8 机房没有影响
很可惜，圣何塞 4837 不论线路质量和稳定性基本与洛杉矶 CN2GIA 线路差不多，DMIT 从不超售，我自己的几个站点都托管在 DMIT 圣何塞 4837 线路，其中最低配置的 WEE 套餐，跑一个日 IP 1000人以上的站点一点压力都没有。
DMIT 圣何塞回程路由
三网变成了直连，线路效果也非常一般。
