We are currently installing and configuring some server speed upgrades which may cause short term and unexpected outages on your sites. We are working hard to get these back online and you will see a long term and consistant speed increase once the changes are complete.
This seems to only be affecting customers with an SSL certificate and who have a dedicated IP address. You can still access your site using HTTPS in the mean time.
Thank you for your patience.
