I forgot to correct the time period which is 10:00 - 12:00 GMT+3.
And i must say that i never until now and only on this 2 hour interval, had constant disconnections or tremendous lags. Even with the melee lag issue i wasnt affected until the last month before migrating to AWS which for the whole server it was unplayable. And i am a melee character but i use only skills.
My connection from the ISP's place, is and was always up without problems.
From the link i posted on my previous post, i saw during the first hour (10:00 - 11:00) all the US located servers having 3000-4000 ms delay while during the second hour (11:00 - 12:00) only the Virginia server which is our server, ranging latency 900 - 4000 ms, while the other US servers had dropped to 300 - 600 ms. And as i said at 12:00 the latency dropped in normal for the distance amount and the game will be until 10:00 tomorrow (unless something will change during maintenance) without any lag or delay
