Potential service disruption in Routing Service

We are carrying out scheduled maintenance on our Routing Service instance. Short disruptions of its service could be experienced today (06.04.2021) from 23:00 to 00:00.
If you receive an error using fdsnws_fetch add the -u parameter with an alternative Routing Service. For instance:

fdsnws_fetch -u [… rest of the parameters]

Thanks for your understanding.
