Bright solstice, friend!
The increases went live just recently and not everywhere. We are slowly updating all realms with new rates. A bit of patience goes a long way. Also, once every event starts there is an auto-broadcast that lets everyone know. We also announced it several times. We do not have a list of all locations on the forums because they change all the time. Also, that is kind of the point of an invasion. Usually, people who are invading you, do not give you a heads up. (even though we do have the announcements, make sure you turn on the system messages in your chat)
