I just received this email from the server tech:
I'm not sure if we will have some down time, but I don't care. I can't stand how slow the site is anymore. I don't know how much of an improvement we'll have, but anything is better. Hopefully it will fly.The new server is installed and we're syncing your sites content...We'll keep you posted when we have this task finished and then we need change the dns entries to this new server.
