Hi guys for those of you that use pi-hole (or similar solutions like adguard home, etc) and wireguard how far away can you be from your wireguard/pi-hole server before latency becomes a major issue?

Also on a side note how many milliseconds of latency would you guys consider to be to slow?

Edit I meant dns latency sorry for not mentioning

I have Wireguard and I forward DNS and my internal traffic from my phone over the VPN to my pi-hole at home. All other traffic goes directly over the Internet, not the VPN. So that means only DNS encounters higher latency.

However, because a lot of companies do DNS based geo load balancing that means even if I'm on the east coast all my traffic gets sent to the West Coast because my DNS server is located there. That right there has the biggest impact on latency.

It's tolerable on the same continent, but once I start getting into other continents then it gets a bit slow.

Would it be better to route that directly? I'm not really understanding the complexity I guess.

Sorry, what do you mean route it directly? Maybe I didn't clarify well enough.

My DNS is routed over the VPN but Internet traffic is routed directly. The problem is the load balancing is done based on where the DNS server is so say Google even though the traffic egresses directly to the internet bypassing the VPN it still goes to a Google DC near my home. Not all websites do this so its not always an issue.

Sorry about that, I missed the part about this being for your phone.
