DNS round robin has the disadvantage of not guaranteeing that the traffic will be equally distributed. This can be a problem if there's a lot of automated traffic.
But, with that said, in term of price, it's unbeatable.
- sieabahlpark 7y agoThe point is at scale you can't guarantee equal but something around there
- song 7y agoThat works well, but if you do ecommerce or a web app for which people write a lot of bots, then the traffic won't necessarily be that well distributed (mostly because users while run bots out of dedicated servers or such and will tend to only query dns once). A bit of an edge case but pretty much the only issue I've had so far which is why I bring it up.
