Request for information: ISPs and P2P throttling

[Demolish]

- ISP: Sky (20Mbps)

- Country of Residence: England, United Kingdom

- When does the problem occur?: Random times.

Occurs constantly throughout the time I'm playing. There's long pauses during combat, when speaking to NPCs, performing actions, mounting & dismounting my. Also happens, during instanced quests, where there are typically very few mobs/objects in the area, the problem arises.

This is an issue I never had in Beta Phase 3, but constantly got it in Phase 4 and launch being Error 90000'd every 2 minutes, lag spikes once every minute or so and predicting mobs next 10 moves leveling 2 jobs to 15 and one to 45.

EDIT: I am on PS3 if that makes a difference?
