EXCLUSIVE, UPDATED, 11:41 AM: Still no word yet on when Nielsen will be getting out those delayed Sunday and Saturday fast-affiliate ratings, but we do know a bit more about what went down – literally.

There was a power outage early Sunday morning in Nielsen’s Global Technology and Innovation Center in Oldsmar, Florida that looks to be the cause. I hear that the power is now back on at the facility near Tampa. I also hear that data collection itself was not impacted, but the measurement company’s systems have to be rebooted to eventually pump those primetime ratings for American Crime, NCIS: LA and more.

“A power outage at our Oldsmar Data Center impacted the availability of some Nielsen applications and the planned delivery of some Nielsen data for Sunday, March 12th and Monday March 13th,” said the company in a statement provided to Deadline today. “We are actively working to resolve the issue and will continue to provide clients with updates as more information becomes available,” they added.

With its primary HQ in the UK, Nielsen moved into the 475,000-square-foot, $80.2 million Oldmar facility back in 2003. Before that, the company based its domestic data collection in nearby North Pinellas.

Previous similar situations like what Nielsen experienced this weekend usually have seen ratings start to trickle in around 1 PM PT – so perhaps history will repeat itself today.

PREVIOUSLY, 9:25 AM: Your wait for last night’s American Crime Season 3 debut, Family Guy and NCIS: Los Angeles ratings numbers is going to be a bit longer today.

Nielsen is experiencing some sort of undefined “technical issue” we’re told and the fast affiliate results for ABC, Fox, CBS and NBC are delayed this morning. On the specifics, things are a little blurry, as Nielsen did not respond today for request for comment by Deadline. There is no indication yet as to when those early ratings for Sunday or Saturday are going to come in.

“It is so frustrating to be left in the dark like this,” one growling network exec told me this AM about the lack of information from Nielsen. “They must know what the issue is, so why not share it with us?”

However, we do know that the matter started sometime on Saturday evening or yesterday morning – which is why there were no ratings for the Scarlett Johansson-hosted Saturday Night Live this weekend.

As well as featuring the Ghost In The Shell actor, the  March 11 edition of the late night show also saw the return of Alec Baldwin in his very popular role as President Donald Trump, this week fighting off an Independence Day-style alien invasion. To give some potential context, the March 4 Octavia Spencer-hosted SNL drew 2.3 rating among adults 18-49. That was down 36% in the key demo from what the last SNL original of February 11 snagged with Baldwin himself as the host. The Hidden Figures actor hosted show last week was steady with the dou of SNL shows that came before the Baldwin hosted one

We’ll update as we get more info on the delay or with the actual ratings themselves – hopefully today.
