On February 18, 2026, YouTube experienced one of its most significant outages in recent months. Users across several countries simultaneously reported being unable to access the website, play videos, or properly use the mobile app. The peak of the disruption occurred during the morning hours in U.S. time zones, when Downdetector recorded more than 330,000 complaints.

Scope of the Problem: The U.S. Leads

According to Downdetector, the largest number of reports came from the United States — over 320,000. The breakdown of complaints was as follows: 18% of users were unable to access the website, 16% reported issues with video playback, and 56% indicated problems specifically with the mobile app.

The outage also affected Europe. The United Kingdom saw more than 37,000 reports, Germany around 7,000, and Italy over 5,000. A significant number of complaints were also recorded in France. In other countries (including Russia, Armenia, and CIS states), disruptions were either not recorded or were isolated.

By midday Moscow time, the number of complaints had dropped sharply as service began to recover. At the time of writing, most users were able to watch videos without issues.

Cause of the Outage Still Unknown

As of publication, Google (YouTube’s parent company) had not issued an official statement explaining the cause of the disruption. In the past, similar global outages have typically been linked to:

  • CDN (content delivery network) failures;
  • Data center issues;
  • Traffic spikes or server update errors.

None of these explanations has been officially confirmed in this case.

Interestingly, the outage occurred just days after media outlets and Reddit users had been actively discussing a new wave of Google measures targeting ad blockers.

Connection to Ad Blockers?

Last week, Android Authority and Reddit users reported that YouTube had begun cracking down more aggressively on ad-blocking extensions (such as uBlock Origin, AdBlock, and others). When an ad blocker is enabled, video descriptions reportedly disappear, and the comments section is replaced with a message reading “Comments are disabled.” Once the extension is turned off, the interface returns to normal.

Many users speculate that testing new anti–ad blocker mechanisms may have overloaded servers and triggered the global outage. However, this remains only a theory — there is no direct evidence linking the two.

What to Do If It Happens Again

If YouTube goes down again, the following steps often help:

  • Restart your browser or app;
  • Clear cache and cookies;
  • Change your DNS settings (for example, to Google’s 8.8.8.8 or Cloudflare’s 1.1.1.1);
  • Temporarily disable ad blockers or VPN services.

In most cases, such outages last from 30 minutes to several hours and are resolved on Google’s end.

In Brief

On February 18, 2026, YouTube experienced a global outage, with peak complaints exceeding 330,000 — primarily from the United States (320,000+), the United Kingdom (37,000+), Germany, and Italy. Users reported issues accessing the site, playing videos, and using the mobile app. By midday, the disruption had largely subsided.
