Heavy Usage

This morning we had a user making very heavy usage of Xamin sending multiple cone search requests per second. Requests piled up in the database and this slowed down the system considerably. Requests that normally took a second could take several minutes. Metadata queries in the interactive versions of Xamin would often time out so that the Web interface was not really working.
We have temporarily disabled access for this IP address.

We’ll be looking at how we can meter usage more effectively in the future and apologize to those adversely affected.
