[ANSWERED]Icecrown caster delay

There is a huge problem with caster delay on Icecrown and it is present here for around 2 months. As far as i know there is no such problem on Frostmourne and Lordaeron, so i guess it isn't caused by network problems from corona isolation. When is it going to be fixed?

We are always trying to improve the stability and performance of the realm but with a high number of players some delay might come up.
