Notional Labs runs its validator nodes on high-spec machines on-site in Hanoi. We use an uninterruptible power supply (UPS) backup and an open multi-path TCP router aggregating three ISP lines for max bandwidth and uptime.

Benefits include:

• We can immediately troubleshoot and fix our nodes.
• No reliance on third parties (companies like Amazon or Microsoft for servers).
• Our machines run faster than the competition.
• Our infrastructure team works shifts in a follow the sun model so there is always someone available to fix issues 24/7.
• We can ensure decentralization for our operations.
