Google and Oracle cloud servers down during UK heatwave


Cloud services and servers hosted by Google and Oracle in the UK have been taken offline due to cooling issues as the country experiences a record heat wave.

When the mercury hit 40.3C (104.5F) in the east of England, the highest on record by a country unaccustomed to such conditions, data centers could not withstand the heat. Some machines were shut down to avoid long-term damage, causing certain resources, services and virtual machines to become unavailable, taking down unlucky websites, and more.

Several Oracle Cloud Infrastructure resources are offline, including networking, storage, and compute provided by its servers in the south of the UK. Cooling systems were blamed and technicians shut down equipment in a bid to prevent hardware burnout, according to a statute update from the Oracle team.

“Due to unseasonable temperatures in the region, a subset of the cooling infrastructure within the UK South (London) data center experienced an issue,” Oracle said at 4:38 UTC on Tuesday. “As a result, some customers may not be able to access or use Oracle Cloud Infrastructure resources hosted in the region.

“Affected service teams have been engaged and are working to restore the affected infrastructure to a healthy state. However, as a precautionary measure, we are in the process of identifying service infrastructure that can be safely de-energized. to prevent additional hardware failures. This action is taken with the intention of limiting the potential for long-term impact to our customers.”

We are told that at least part of Oracle’s cooling infrastructure went down around lunchtime UK time.

Oracle isn’t the only IT giant to report temperature-related outages. Google Cloud said a number of its products “experience high error rates, latencies or unavailability of service” when served from systems located in europe-west2-a, which is one of its facilities in London .

These issues affect various storage and compute-related services, including BigQuery, SQL, and Kubernetes. Google acknowledged the downtime at 1615 UTC. This breakdown has, on the one hand, beaten down WordPress websites hosted by WP Engine in the UK, which were powered by Google Cloud.

“There was a cooling-related outage in one of our buildings that hosts the europe-west2-a zone for the europe-west2 region,” according to another Google. advisory.

“This caused a partial capacity failure in this area, resulting in VM downtime and loss of machines for a small group of our customers. We are working hard to bring cooling back online and build capacity in this area. We do not expect any additional impact in the europe-west2-a zone and running virtual machines should not be affected.

“To prevent damage to machines and prolonged outage, we have powered down part of the zone and are limiting preemptible GCE launches. We are seeing a regional impact for a small proportion of newly launched persistent disk volumes and are working to restore redundancy for affected replicated persistent disk devices.”

The register asked Oracle and Google for additional comments.

Extreme temperatures have also sparked fires in parts of England, affecting motorway traffic, rail services and electricity, with Luton Airport also temporarily closed due to a melting runway. We’ll let you know if other Internet services are also affected. ®
