With T7750 calling for the decom of cp3 (something I have always advocated since moving across the OVH), we need to re-balance and evaluate how geo-located requests are balanced among datacentres in GDNSD.
This will mostly be based on average latency to a server, I mind expand to a more country based approach if there are significant benefits to splitting a continent in half (mostly around Asia/Oceania?) given we only have two cache PoPs.
There is also a question of whether we would benefit form a third-external PoP, reviewing available options on some large VPS providers, I'll provide an additional analysis of this to see if potential data would back up further investigation into this - or whether investing more in either GB or CA would bring the most benefit.
**Key**
* CA = Canada
* GB = Great Britain
* SG = Signapore
* AU = Australia
| Continent | Country | -> CA | -> GB | -> SG (hist) | ->AU (OVH) | Best DC? |
