And hour after the 'glitch', United just tweeted that the ground-stop has been lifted...
UPDATE: The ground stop has been lifted. We’re working to get flights on their way. We apologize for the inconvenience to our customers.

Yet again, a so-called IT glitch has wreaked havoc with an American airline.
A ground stop is in place for domestic flights due to an IT issue. We’re working on a resolution. We apologize for the inconvenience.

As CNN reports, United Airlines has grounded all domestic mainline flights Sunday night because of a computer problem, according to United spokeswoman Maddie King.
"We have issued a ground stop for all domestic mainline flights due to an IT issue," King said.
"We are working as quickly as possible to resolve this issue and get our customers to their final destinations. We apologize for the inconvenience to our customers."
Of course this is not the first time computer glitches have hit airlines...
In October, United flights were delayed for hours because of a computer problem, causing a social media firestorm. United said it experienced an issue with its weight reporting system that was later resolved.
In September, British Airways suffered a computer problem that caused delays and long lines at airports in the United States and Europe.
In August, Delta was forced to cancel around 2,000 flights after a major system failure. That came only a few weeks after an outage caused more than 1,000 cancellations at Southwest Airlines.
So far no mention of the Russians being to blame.
