Can you restart the server? It's lagging!
A server restart is not a silver bullet to server issues; instead it tends to be a placebo given there are fewer players online temporarily - only for the issues to resurface once everybody has reconnected. You can post in the relevant discord channel to notify the staff there are issues with the server you are on or alternatively you can submit a support ticket.
Please note, our Systems team already have a suite of monitoring tools at their disposal and are typically alerted ahead of time if there are any major technical issues arising on servers.
