Hi @phildunlap ,
Thank's for the reply, somehow I figured it out...
The easy explanation is a bit out any rational answer... => I have to use the grey cloud
The DNS for our domain name is controlled by CloudFlare. And the traffic was directed through the 'wrong' path.
"Orange cloud" (proxied) Load Balancers have an automatic TTL - this means that CloudFlare will announce CloudFlare IP addresses externally, but will protect (mask) your origin server IP addresses. Any changes to your Load Balancer will propagate within seconds inside Cloudflare, including any failover events. The primary benefit here is that external DNS resolver caches that do not respect short (e.g. 30s) TTLs will not impact the failover speed of your Load Balancer.
"Grey cloud" (DNS only) Load Balancers may be configured with a TTL from 30 seconds to 10 minutes. CloudFlare will serve the addresses of the (healthy) origin servers directly but relies on DNS resolvers respecting the short TTL in order to re-query Cloudflare's DNS for an updated list of healthy addresses.
Anyway, by using the orange cloud, all the charts were 100x200 px. and I have absolutely no clue why...
Maybe your devs will laugh loud seeing this post. If anyone knows an explanation, I would be glad to know
