Ran the tests and it seems like London is the best.
Created a droplet in each area pinged then all from Gauteng In South Africa
The droplets were destroyed after the test, so pinging then now probably will not work
The results are below
Hope this helps somebody
Not to hijack the thread, but are there any future plans for opening a DO data center in South Africa?
I know there will be huge support for DO services in SA. I personally prefer using DO over the local Cloud solutions but they still rule the roost with low latency.
