Shutdown of aleph.lobid.org

[dr0i]

Since two years or so we have switched from aleph (MAB) to Alma (MARC21) in our lobid.org/resources .
Nonetheless we serve the old data at aleph.lobid.org/resources. Data is way outdated but some people use(d?) it to lookup old IDs to match them with the new Alma-IDs etc.
This old system, along with https://github.com/hbz/mabxml-elasticsearch , uses some resources at our server. If no more needed we can save those resources.

Is there anybody out there using this old services still - or can we shutdown?
