m2pc writes "The US Postal Service is experiencing major server issues for its shipping API web services. After spending about an hour debugging my own eCommerce software for a client, I found the problem was with the USPS shipping servers being unavailable. Further research showed that message boards for OS Commerce and other e-Commerce packages are filling with posts from angry users who are experiencing crashing Web store applications and frustrated customers. Developers are scrambling to find interim solutions, from hard-coding fixed price shipping, to 'rolling their own' shipping calculation APIs based on the USPS Fixed Rate Zone Tables, to disabling the USPS option altogether. One user reported yesterday that a call to USPS yielded the response 'we expect it to be down all day.' As of 9:20 AM PST the service is still unavailable."
