Possible reasons for "downtime" could include but are not be limited to:
What checks can I carry out to verify that my service(s) is/are indeed down? (Not necessarily in this order)
If you've carried out a few of the above checks and you still can't access your service(s), please review our Service Issues page which is updated with the latest information about issues if there are any. We ask that you do not contact us if the issue affecting your service(s) has been posted on that page - please keep visiting and keep yourself updated instead.
Should nothing appear on that page, please create a Support Ticket with our Technical Support department providing as much information about the problem as you can, and any diagnostic steps you took to try and resolve the issue(s).
