Cloudflare Blames Google Cloud For Mass Services Outages

“This is a Google Cloud outage,’ a Cloudflare spokesperson tells CRN.

Cloudflare blamed an outage at Google Cloud for a number of products and services by the content delivery network vendor going down Thursday.

Google Cloud also saw a wide variety of products and services go down, and users of popular third-party applications ranging from Spotify to Discord reported outages—although it wasn’t immediately clear if those outages were related to Google Cloud’s issues.

“This is a Google Cloud outage,” a Cloudflare spokesperson told CRN in a statement Thursday. “A limited number of services at Cloudflare use Google Cloud and were impacted. We expect them to come back shortly. The core Cloudflare services were not impacted.”

Cloudflare said on its status webpage at 20:57 Coordinated Universal Time (UTC)—1:57 p.m. Pacific—that “all Cloudflare services have been restored and are now fully operational.” The company said it continues to “watch platform metrics to confirm sustained stability.”

Cloudflare, Google Outages

In a statement to CRN, a Google Cloud spokesperson said that the company is “currently investigating a service disruption to some Google Cloud services” and referred to its public status dashboard for the latest updates.

In an update published to Cloudflare’s status page Thursday at 19:57 Coordinated Universal Time (UTC)—12:57 p.m. Pacific—the San Francisco-based company blamed “an outage of a 3rd party service that is a key dependency” for its “critical Workers KV service.”

“As a result, certain Cloudflare products that rely on KV service to store and disseminate information are unavailable,” according to the post. “Cloudflare engineers are working to restore services immediately. We are aware of the deep impact this outage has caused and are working with all hands on deck to restore all services as quickly as possible.”

Google Cloud updated its status page at 2 p.m. Pacific to say that it has “implemented mitigation for the issue in us-central1 and multi-region/us and we are seeing signs of recovery.” The us-central1 region includes Iowa.

“We have received confirmation from our internal monitoring and customers that the Google Cloud products are also seeing recovery in multiple regions and are also seeing signs of some recovery in us-central1 and mutli-region/us,” according to the vendor. We expect the recovery to complete in less than an hour. We will provide an update by Thursday, 2025-06-12 14:30 PDT with current details.”

An update about 10 minutes later added that multiple Google Cloud Platform products saw “varying level of service impacts with API requests.” At 12:09 p.m., Google reported that “our engineers are continuing to mitigate the issue and we have confirmation that the issue is recovered in some locations.”
