UPDATED 7:05 p.m. PT: CBS blamed the live steam problems on a glitch in All Access’ ability to verify the locations of some users.

“Some users experienced temporary difficulty accessing the live online feed of the Grammys. Our location services provider had a brief issue verifying user location. That issue has since been resolved and all users are back online,” a CBS Interactive spokesman said.

The problems are said to have affected a small percentage of the record number of people viewing CBS All Access’ live stream. However, some users are still reporting problems via social media.

PREVIOUSLY: CBS appears to be struggling with the demand for the live stream of tonight’s Grammy Awards telecast as many viewers are complaining of being unable to watch the show via the CBS All Access SVOD service.

CBS aimed to capitalize on viewer interest in the Grammys by offering a free one-week trial of CBS All Access, hoping to whet the appetites of potential subscribers to the service, which costs $5.99 a month. But viewers in multiple markets reported they were unable to load the live stream. That could be a result of demand overwhelming CBS’ ability to serve up streams.

Another problem could be viewers trying to watch in markets where the live TV stream is not available via CBS All Access. Those are markets where CBS has yet to reach an agreement with its affiliate station on a revenue-sharing partnership for All Access. CBS said earlier this month that about 85% of its affiliates are on board with CBS All Access. (Here’s a list of the 130 markets where the live stream should be available.)

A CBS rep had no immediate comment on status of the All Access stream.

With some encountering problems with the All Access stream, links to bootleg live streams of the Grammy Awards were circulating widely in social media, although CBS appeared to be cracking down quickly on those unauthorized streams.
