crimeandpunishment writes "A planned server outage turned into an unplanned glitch for the Internal Revenue Service, and it comes at a very bad time. The IRS planned the server outage for the holiday weekend ... but today they couldn't get the system back into operation. This week is the deadline for filing 2009 tax returns for taxpayers who got extensions. So far it's not having a huge impact since the shutdown only involves the updated version of the e-filing system, and most programs used by large tax companies like H&R Block will default to the older version. There's no estimate on when the system will be back up."
