Investigating - We are currently experiencing a service performance issue affecting multiple data centers. You may notice an increased number of fail opens and timeouts, resulting in delays or failures when making requests.

Our engineers are currently working to identify the root cause and implement a resolution. Updates will be provided as new information becomes available.
