USPS Zipcode error?

[grace83]

I've been getting errors today with the USPS module. It's been working fine right up until today, but now is saying:

"We are unable to find a USPS shipping quote suitable for your mailing address and the shipping methods we typically use.
If you prefer to use USPS as your shipping method, please contact us for assistance.
(Please check that your Zip Code is entered correctly.)"

It showed this for a customer, as well as now with my trying my own. Both have worked fine in the past, and I haven't changed any settings recently.

I've removed and re-installed the module, to no avail.

I started getting the same error today...

Something with Zencart or something with USPS?
