“We’re pleased to report that the facility has returned to normalized operating conditions.”
All our connectivity and services are fully restored and we are also observing the usual ambient temperatures.

Update
We are observing the temperatures continuing to decrease in the facility.

Update
As per the facility:
“We truly appreciate your patience as we worked to resolve these issues. Throughout the day, we have completed the restoration of Chiller C and installed temporary cooling and heat removal devices across the facility. These actions have meaningfully reduced interior temperatures to a near normal operating levels. Over the next 60-90 minutes our teams will make necessary connections, test and commence operation of the temporary chiller adding additional redundancy. “

Monitoring
We are observing further reduction in ambient temperatures.
Arelion capacity in Phoenix is back online.
We are pleased to confirm that the affected services have been restored.
The third chiller has been restored, and temperatures at the Phoenix site are stabilising. We will continue to monitor the service closely.

Update
NTT with regards to packet loss / increased latency affecting some destinations in Phoenix: The carrier has provided an ETR of 2030 UTC
Posted Aug 13, 2026 - 21:16 BST
Update
With the ambient temperatures reducing further, all networks devices are now out of alarm state. We have restored VPS/Cloud Hypervisors as well as known affected Dedicated Servers. Cloud / VPS services as well as Dedicated Servers should still be considered at risk as the temperatures remain high and close to threshold of precautionary OS shutdown.
If your service is still affected, please let support know so we can investigate.
It's important to note that the datacenter is still facing issues and the cooling capacity remains reduced. It's equally important to note that our carriers continue to facing issues. Arelion capacity is down. NTT capacity remains up but NTT reports capacity issues with their own carriers. We are observing odd packet loss with GTT from time to time. The effects are expected to continue for hours after cooling capacity is restored.

Update
The declining ambient temperature trend in Radius DC Phoenix continued since the last update. While we tried, the ambient temperature remains too high to restore the affected services. We are re-assured about the stability of services that have not been affected by some of our network equipment components temperatures going out of alarm state.
We are continuing to observe the temperatures and we will restore the affected services when its safe to do so. We will pass along any meaningful updates as we observe them or receive them from the facility.

Update
We have received the following update from the facility:
Phoenix Datacenter is experiencing elevated white space temperatures caused by multiple utility bump events attributable to overnight storms in the area. The facility has on-site vendors working rapidly to resolve the situation and restore adequate cooling. Site technicians have activated mitigation efforts to reduce rising space temperatures. Phoenix Datacenter has thus far restored Chiller D into operation as of 8:15 am local time. Ongoing remediation measures include the following action items (local time):
Temporary on floor cooling and heat removal equipment added (approximately 10:00 am) Chiller C restoration (targeted 12:30 pm) Additional temporary chiller and temporary backup generator added (targeted approximately 4:00 pm)
At present the temperatures remain high which may be service affecting for your services at this location. Some of Dedicated Servers have entered a thermal shutdown state. All our Cloud/VPS nodes in Phoenix entered thermal shutdown state. For those servers, the ambient temperatures remain too high to restore the service. We are continuing to monitor the situation.
As for the network, majority of our external connectivity is currently up. We are observing some blips, from time to time via transits whose routers are located in the same facility and affected by the same issues. Our routers remain unaffected at this stage. Arelion capacity is currently unavailable in Phoenix as their router remains affected and we are observing no light from them. Arelion is aware and has an engineer on site.
We'll update this page once meaningful updates become available.
Posted Aug 13, 2026 - 18:23 BST
Update
We have observed the temperatures to have peaked and we are now see an early trend downwards.
We'll provide updates as soon as any meaningful update from either facility or our observations becomes available.

Update
The site has confirmed they are actively working with their vendor on site to resolve the cooling issue.
We will provide updates as soon as any meaningful ones become available.
Posted Aug 13, 2026 - 14:57 BST
Update
Site has confirmed they are currently experiencing cooling issues at their data centre due to recent power outages. As a result, temperatures within the facility have increased, which may have caused temporary disruptions to your services.
The site has assured us that they are actively working to resolve the issue and restore normal operating conditions as quickly as possible.
We will continue to provide updates as more information becomes available.
Posted Aug 13, 2026 - 13:50 BST
Update
Majority of our Public Cloud/VPS hypervisors at Phoenix, AZ has reached critical temperature and entered thermal shutdown. The affected services will remain down until the cooling situation is resolved.
Incident escalated to the highest level at Clouvider. We are awaiting the site's response.
Posted Aug 13, 2026 - 13:41 BST
Update
Our connectivity to Arelion at Phoenix has gone down - we observe no light from the carrier. Our traffic has automatically re-routed. We are engaging Arelion to check on their equipment. We assume they are affected by the same cooling issues as we are.
Posted Aug 13, 2026 - 13:39 BST
Identified
The temperatures are rising rapidly with some devices reporting warning states. We are waiting for the update from the facility.
Posted Aug 13, 2026 - 13:15 BST
Investigating
We are observing elevated temperatures in our Phoenix, AZ datacenter and engaging the site to provide more information.
