I noticed all of the sudden that it's taking about 1+ MINUTE for the USPS.php shipping module to return postage results. This just started happening within the last 24 hours. Can anyone else confirm it?

If I uninstall the module, the shipping estimator and checkout page loads quick. If I install the module (using the latest version B released by the ZC team), the long delay occurs and it causes people not to complete the checkout process because they think it's hung.

Is something going on with the USPS because if so, I would imagine others are experiencing this same delay.
