UPDATED: Roku streaming players and Roku TVs were affected by an outage that lasted for several hours Tuesday, with numerous users reporting on Twitter that they couldn’t load Netflix, YouTube and other channels on their devices. Roku acknowledged the outage on its website, telling users around 9 p.m. PT that it had been resolved.

A Roku spokesperson told Variety Tuesday night that the outage had only affected a small number of users, but a number of users had taken to Twitter to voice their confusion about a puzzling detail: Instead of the streaming apps of their choice, they got to see a warning from the FBI, informing them that the channel in question had been removed “due to repeated claims of copyright infringement.”

Hey @rokusupport here is the message when trying to launch YouTube on my Roku TV. Has Roku removed the @YouTube app? This seems very odd to get a FBI warning. pic.twitter.com/i8mwznWZQx — willwinter (@willwinter) May 15, 2018

Other channels affected by the outage include FoxSportsGo, FandangoNow, Hotstar, YuppTV and Gaia, according to user reports on Twitter.

Roku said late Tuesday evening that the outage had been resolved, and advised affected users to install a system update:

We're back! Netflix and YouTube are working along with most channels in the Channel Store. Go to Settings> System> System update> Check now. For some channels, you may need to log in again. Thank you for your patience. — Roku Support (@RokuSupport) May 16, 2018

Roku has in the past displayed similar warnings after taking down private channels dedicated to streaming content from unauthorized sources. A Roku spokesperson told Variety Tuesday that the warning accidentally went up in this instance.
