It's been happening to us and others too, though we're using CIM. (Sometimes the CIM connection terminates unexpectedly; other times, we get an E00001 No transaction response; I'm pretty sure CIM just relays to AIM underneath, so that could be consistent behavior among their systems.) Other similar reports on Twitter: https://twitter.com/search?f=realtime&q=authorizenet&src=typd
I had a Live Chat agent "escalate" it a few hours ago, but I don't expect we'll receive any kind of acknowledgement, update, or root cause analysis from Authorize.Net based on their previous behavior in such outages -- we can just wait for it to start working again. Because it is intermittent, it'll be hard to know when it's resolved.
System.ServiceModel.CommunicationException: An error occurred while receiving the HTTP response to https://api.authorize.net/soap/v1/Service.asmx. This could be due to the service endpoint binding not using the HTTP protocol. This could also be due to an HTTP request context being aborted by the server (possibly due to the service shutting down). See server logs for more details. ---> System.Net.WebException: The underlying connection was closed: An unexpected error occurred on a receive. ---> System.IO.IOException: Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host. ---> System.Net.Sockets.SocketException: An existing connection was forcibly closed by the remote host
