For a few months now, all transactions are taking approximately 22 seconds. Whether charging a credit card, or adding a credit card to the CIM, etc.
We are running on ASP.NET and .NET Framework 4.8, using the Authorize.NET .NET SDK.

When retrieving a credit card from the CIM, it returns a response in under a second. VOIDing a charge takes over 21 seconds. Adding a credit card to CIM takes over 21 seconds. Charging a credit card takes over 21 seconds.
