My pod need to query to external services a lot and i'm getting significant latency for outbound connections.

curl google.com

I tried verbose curl as well. its not the DNS
```
curl -w "dns_resolution: %{time_namelookup}, tcp_established: %{time_connect}, ssl_handshake_done: %{time_appconnect}, TTFB: %{time_starttransfer}\n" -o /dev/null -s "google.com" dns_resolution: 0.017371, tcp_established: 1.019982, ssl_handshake_done: 0.000000, TTFB: 1.033671
