Hello,

we are a growing network and it is time for us to implement a routing
by region solution. We are thinking anycast ?

What are your thoughts ?

What is the best way to implement it ? Any useful links ?

Please advise.

Thank you.

To be honest that is a bit over kill. Try looking at a DNS provider
that provides Geo and have a "pool" A record. I believe NS1 and
Route53 do that.

`19:13 -!- There are 20 users and 318 invisible on 23 servers`

`19:13 -!- 45 operator(s) online`

`19:13 -!- 57 channels formed`

`19:13 -!- I have 50 clients and 2 servers`

`19:13 -!- 50 69 Current local users 50, max 69`

`19:13 -!- 338 342 Current global users 338, max 342`

For a max of 342 users... One server would be enough.

Yes! I've had this one saved in my RSS reader for years now, just in
case it ever comes up. Disclaimer it's from 2016 I don't know if the
information is still current, but it's a decent starter.

As the other comment mentions though it may be way waaaaay easier to
use a GeoIP DNS method using something like Amazon's Route53

IRC over anycast just wouldn't be stable. Unless you mean anycast DNS?
Then this is easily doable via most of the larger DNS hosts.

But this... it's really not worth it.

This is good advice IMO. Do get a couple of servers on different
places in the world with DNS being the source of truth based on geo.
My (non-IRC) experience with global anycast has been it's hard to
control.
