Constant ERROR pages when using selling / store features.

[calypso.shop]

Hey! I'm a 5 year Top Rated seller and have for the past month every day been getting hours long spurts of consistent Error pages when listing/revising listings/just general eBay use... (have to reload pages up to 20-30 times before it works for a moment) There is no other connection issues across my computer at the same times this is happening, it's strictly an eBay issue. What is going on?
