so recently we encounter issue with some of our services can’t resolve hostname that had been setted up before. Any of you guys have same experience? if yes can you share it with me what is the common cause or how to solve it?
P.s : the one thing we suspect as the root cause is the high load of the services, but we still digging up more
thank you so much everyone !
