Server lags for last week

I' am experiencing huge server lags during the "rush hour" so in the evening e.g. 6 p.m. to 10 p.m. I am 100% sure it's server lags, like it used to be before Easter event (huge lags, delayed buffs etc). I think there is so much players and the server cant hold it. (Like test server when all people are testing to get rewards).
It is happening in the chrome and firefox too, I cleared my cachce in both browsers and also using the newest flash.
Are you planning any server upgrade to improve server HW or its connection problem?
Thanks.

Hi there BattleOverlord,

We have reported the serious lag issue.

Many players have experienced this in the last few weeks unfortunately :(

The dev team is aware of this, I am certain they are working hard on improving server stability.

Watch out for upcoming logs.
