Finds out why our system will not open on this device, and what to ask for.
This page tries to open a number of our own web addresses from this device and times what happens. From the pattern of what works and what does not, it works out whether the problem is this device, this network, a security filter, or us — and writes it up in plain English.
It takes about a minute. It is safe to run on a work computer.
At the end you get a plain text report. You can read it, edit it, delete anything you would rather not share, and then choose whether to send it — or show it to your IT team first.
This list is generated from the page's own settings, not typed out separately, so it cannot fall out of step with what the page actually does.
These are optional, and they make the result far more useful.
This is checked on this device only and is not sent anywhere. Email security products often rewrite links, and that alone can stop them working — but it is invisible unless somebody looks at the link itself.
Starting.
Some checks deliberately wait for a slow failure, because how long a connection takes to fail is itself part of the answer. Please let it finish.
This is yours. Read it, edit it, remove anything you would rather not share. Nothing has been sent.
If your IT team would rather review this first, send it to them, not to us. Everything in it is about your own network, and it is written to be read. The information page for IT explains every check.
