I have been saying this for a while - that 15s backup of everyone's entire inventory is utterly asinine. I'm really not sure why they can't seem to spot that and do something about it. There are ways to do away with it, ways that have been suggested already. And when their entire network seems to be under such huge stress all the time as they claim... yeah, it's high time to get rid of that, it apparently isn't viable at this scale.
