In Vietnam you can get solid fibre 30/30 is pretty standard. The issue is international speed. If youโre dealing with the big guys, they are figured out their own routes into the country so all their services are fine. If your server that you want access to is not with the big guys and youโre effectively using the public internet for connectivity, then it is hit and miss. Latency is usually fine and matches the distances. Itโs bandwidth that can become an issue. I average around 2-3mbps both ways, it bursts up to 10-15mbps sometimes.
So when looking check if FTTP/H is the norm, thatโs good sign the country is going to be fine for general connectivity. Then check the news about international connectivity issues. Vietnam has a few cables, however they often get cut, theyโve nearly finished repairing one of the new ones, so hopefully that will help.
Also here in HCMC 30/30 goes for about US$60/month.
Big guys: Google, Microsoft, Amazon, Netflix, Rackspace, etc
