When users try to add a paragraph to the translation it may fail due to technical reasons at different points:

• CX Server not being reachable (e.g., due to network issues) will make it impossible to use Machine Translation, and even copying the source paragraph as a fallback.
• A translation service not being reachable will make impossible to use such service, but other services or copying the source content could be considered as fallbacks.

This ticket is intended to capture how to communicate these issues and which approach to follow in order to cause the least disruption to the user. We probably want to have a generic handler, that may have some specific behaviour for some special cases if needed.

Design solutions to be explored.
