I've had mine open also since earlier this morning and it seems to be working fine. I am using the score sender at the moment. I did try and use the auto buyer but visiting the shops was taking a while so I left it. I think this was my internet connection though.
I just started using and contributing with a little cash recently on Neocodex and have been enjoying the community thus far, but I noticed the same thing with mine - main shops seem to be running a bit slow too lately so was wondering if the downtime now and the slow issue are both dreamhost problems?
