A statement on Akamai's customer site said the company "is aware of a service interuption earlier today affecting content delivery. We have identified the root cause and have implemented the fix.

It's not yet clear whether today's delays are due to increased patching by tardy network administrators, or some other cause. Microsoft said it addressed last month's performance problems by "adding resources to support Windows Update."
Dynamically updating performance charts for Windows Update are available here.
