Since you say it is a host problem and you try to monitor it I dont get the context? Than when it is a host problem, for DEDICATED SERVERS it just can be rooting, cause all other Faults, like DNS or other Problems come from the ServerAdmin...so actually it sounds very weird, what u say their. SO CAN WE SEE PLS THE TICKET SUPPORT FROM YOUR HOSTER WERE HE SAYS ITS A HOSTERPROBLEM?
This lil short useless Informations are useless since we know that not all what you try to sell us is the TRUTH. So a lil bit transparency maybe?
Screenshot? Hoster Support Mail? 24h Monitor Mail since i bet you use a Monitoring Software? The Alertsite from the Monitoring Software? (screenshot)
So far....
Than actually just to say it, this what happened for example on Neltharion the last days, this lag spikes, without Serverdowns, or specificly said from 9 Lag Spikes, 1 Serverdown, this simple looks like a stresstest from Kali or on LOIC so maybe check the logs due to this 2 things cause it wouldnt be the first time, that ppl try LOIC on Warmane.....
