So on Miller today I got the typical ping spike behaviour most have seen lately. Your ping would be fine, then spike to 1000+ms, then go fine again, then spike, etc. The weird thing is that relogging (sometimes several times) fixes it. Which seems to indicate that it depends on what server you get assigned to (I assume they use some sort server cluster setup). So next time it happens, try relogging, check your ping, relog again if it still happens. The success rate so far is based on a small sample of players, so this is not a guaranteed fix, but you don't got much to lose by trying.
