From the first paragraph of the note:
In order to facilitate systems and programming changes, the IRS today notified tax-exempt organizations that the IRS Modernized e-file (MEF) system will not be available from January 1, 2012 through February 29, 2012 for electronic filing of Forms 990, 990-EZ, 990-PF and 1120-POL information returns. The IRS is suspending the availability of the system to implement changes to IRS programs and systems for the 2011 tax year. The 990-N e-postcard filing system will not be affected by the temporary suspension of the MeF system
[...] The IRS’s system for NPOs to electronically file their 990s will be down for January and February while the IRS updates their systems for the new filing year. See my post here. [...]
