It could be one of the three:
1. iTunes store is currently having a technical issue with their own server. Solution: wait and try later.
2. Does your internet explorer or other web application still functioning? It might be your own connection. Solution: Restart your modem and contact your local internet service provider.
3. Your iTunes may be corrupted. Solution: Uninstall your iTunes and download a fresh copy from apple website.
Hope it helps
