Sometime late lastnight my ATT cable shot up to 99% utilization and continues to do so 10 hours later. On checking my firewall, I discovered numerous computers trying to access UDP port 1434 on my computer. Seems like a DDS attack gone amuck.
If you have cable/DSL and are always online without a firewall, you may want to get your O/S to temporarily disable UDP port 1434.
