Erris writes "As commentators like Ars Technica slam WGA as deeply flawed, Microsoft is blaming human error and swears it won't happen again. 'Alex Kochis, Microsofts senior WGA product manager, wrote in a blog posting that the troubles began after preproduction code was installed on live servers. ... rollback fixed the problem on the product-activation servers within 30 minutes ... but it didnt reset the validation servers. ... "we didnt have the right monitoring in place to be sure the fixes had the intended effect"' Critics were not impressed. 'A system thats not totally reliable really should not be so punitive, said Gartner Inc. analyst Michael Silver. Michael Cherry, an analyst at Directions on Microsoft in Kirkland, Wash., said he was surprised that it was even possible to accidentally load the wrong code onto live servers ... [and asks], "what other things have they not done?' This is not the first time this has happened, either."
