   investigating
   We are currently investigating elevated temperatures affecting the TEB4 data center. Due to a heatwave advisory in New Jersey, the facility is experiencing an air conditioning issue that is impacting cooling within the data center. The facility team is actively working to restore normal cooling operations as quickly as possible. At this time, some services may experience degraded performance while we closely monitor the environment and take appropriate measures to protect customer equipment. We will provide additional updates as more information becomes available.
