High server latency after DNS A Record Setup
i use DO for my wordpress community website with Ubuntu 14 and managed with server pilot. It works really nice and fast.
I tested the website and the server latency is very low (30ms - 80ms) with a site load speed from amsterdam with 1.16 seconds. This is great.
Otherwise if i test the same website with the domain the server latency is very high (800ms - 4000ms) with a site load speed from amsterdam with 2 - 5 seconds which is very bad.
The higher load time is only affected from waiting of the server.
The Ip-Adress from the server is: 220.127.116.11
and the domain is juststartup.de
I tested some different DNS settings. The first one is that i use the Name Server from DO, but in this configuration i'm not able to use the email client from my Domain provider. The server latency is high like described.
Now i use the setting that i only configured an A record setting on my domain provider to the server ip address. Server latency is also high.
I'm sure that the bug is in the DNS/Domain/Server configuration. Would be great if anyone can help me, how i have to configure or how i can find help.
Thank you in advance.
