Canadians can go back to filing their taxes online today after a glitch in the hardware systems shut down the tax services yesterday.
The agency had to issue a blanket apology, along with multiple individual ones on Twitter.
But by early evening, the agency was tweeting its gratitude for the patience of Canadians, saying the hardware issue had been fixed and services were back up and running again.
The agency first notified the public yesterday morning that its website wasn't working, although some online users reported that tax-filing services had become inaccessible as early as Sunday night.
The outage, which the agency chalked up to technical issues, affected a number of C-R-A services.
The services are used heavily at this time of year for Canadians filing their taxes.
Work to fix the problem roped in Shared Services Canada, the federal government's centralized information technology shop.
The deadline to pay any taxes owing is April 30th.
