IRS blames Tax Day woes on glitch in file that houses personal records - The Washington Post

Perhaps ran out of spare vacuum tubes...

"The Internal Revenue Service’s online tax filing systems failed widely on Tax Day because of a hardware “glitch” in the part of the agency’s operating system that houses taxpayers’ personal tax records, according to the tax collection agency.

The malfunctioning of IRS’s “master file” was discovered around 4 a.m. Tuesday, the biggest tax-filing day of the year. The impact of the problem spread because several other IRS systems rely on data from the agency’s “master file” to function, the IRS said in a statement to The Washington Post.

The IRS emphasized there was no reason to believe taxpayers’ private data had been breached. “There’s no data loss,” the agency said. “Taxpayers have nothing to be concerned about.”"
