Network connectivity guidance / issue busting

Networks can be insecure and unreliable by their very nature. However, there is a chain of components that together can work to make them more secure and performant and at PKB we aim to leverage that.

Therefore, to securely exchange data every link in this chain needs to work seamlessly together. E.g.:

Without a working low level network tier there is no way a service can resolve domain names.
Without capability to resolve domain names to IP addresses, clients won’t be able to find our servers.
Without firewalls allowing traffic, packets won’t be able to flow both ways.
Without a shared set of supported algorithms and some seed trust to selected 3rd parties data cannot be exchanged efficiently and securely over a functioning lower level network tier.

Occasionally one ore more of these links will break and connectivity will be lost. This could be a PKB issue or an issue at source.

This documentation aims to help you to self diagnose some of the more common problems that could be causing an issue.

What should you do when you cannot connect to a PKB endpoint?

Check our status page to see if PKB is experiencing any issues.
If the status page is not showing any issues, then run through our checklist for sending organisations.
If all items on the checklist look OK and the issue still persists then please raise an issue with us.
