Here is Boardhost's reply re- the board being slow.

Hi Norman
The “Server too busy. Please try again momentarily.” message simply means that at the moment your request reached the server, it was receiving more traffic than it could handle at that instant. This can happen when there is a sudden spike in automated traffic (such as bots or crawlers) or a large number of users accessing the boards at the same time.

We are actively addressing the issue by blocking and rate-limiting abusive traffic to restore normal performance. Most users should already be seeing improvement, and service should continue to stabilize as these protections take effect.

We appreciate your patience while we work through this.

Thank you,
Boardhost Support
