Treasury website temporarily crashed due to high demand for I Bonds this week|futureatlas.com|CC BY 2.0

To temporarily beat inflation, everyone flocked to the Treasury Department website this week to purchase Series I savings bonds, and the high demand crashed the site for a while.

The crash means some of the requests cannot be processed by today; to lock in the 9.62% rate, all requests should be processed by the October 28 deadline.

“We cannot guarantee that your bond purchase will be completed before this deadline if your account or purchase requires additional customer support for issues such as identity verification,” the Treasury announced.
