Details: ChangeIP: $2.49/month/512MB RAM/20GB SSD space/Unlimited traffic/KVM/Los Angeles/DDOS protection The network is good, and the system I/O is very good after changing the node. The replaced node is in LA VPS Node 3.
Judging from current tests, the system has high I/O, unlimited traffic, good performance, and large space. After a 50% discount, it is very cost-effective! Annual payment is recommended! Because discount codes will expire, especially this kind of permanent 50% off discount, which is generally a one-time discount. 1.
