When an expert sends an SMS text message, I had been looping through the list and sending the message to each phone number in real time. If the connection to Twilio was slowed down for any reason, this would affect all of the messages sent in that batch. The messages are now put into a temporary database table and processed in an orderly fashion. One timeout won't affect the sending of messages to any other phone number. Please let me know if you experience any problems receiving sms text messages for trade alert services going forward.
