Anyone can recommend the server?
At least one in each location (can be multiple providers):
Orange, Irvine, Fullerton or Los Angeles (CA) - NOT san diego, NOT san jose, etc.
San Francisco, CA - NOT sj/sac
IPv6 native, at least /112 (no single IPs, nonnegotiable)
IPv4 min 1 (SWIP if possible)
10-15GB disk (must be able to scale up to accomodate demand)
KVM/VMware/etc -- **NO fake virt, nonnegotiable*
This is a slave database server, general internet traffic should not hit it. No ddos risk, no protection is needed There will be more inbound than outbound traffic. Prefer $10-30 USD
