I am located in the USA.

I've noticed my WiZ bulbs are querying DNS for eu.mqtt.wiz.world.

DNS responses for this domain appear to be load balanced in some capacity as the response varies. Sometimes the IP returned appears to be located geographically in the USA while other times it appears to be located in Ireland.

I’d just like to bring this to your attention in case your intent is to load balance and direct traffic to an appropriate data center based on the geographical origination of the request. Surely latency to Ireland would be higher than stateside.
