evenings usually 7pm - midnight

Absolutely unplayable - basically clicking on an NPC freezes you in place and takes between 1min and 5 min to respond.
Cant participate in FATEs or even play in populated areas as the latency means any action I take does not get a response for c.10 - 30 seconds if at all.

Around these times the latency is absolutely fine.
