We’re currently investigating an issue with our provider (Rackspace) that is causing sites to be slow or intermittently down. We’ll provide an update as soon as we have more details.
Update (4/22/14/ at 12:43 PM Central): Things have now stabilized and site availability and performance have returned to normal. If you continue to experience issues or have questions, please contact our helpdesk by submitting a ticket via https://my.pressable.com, thank you!
