We are currently doing some heavy maintenance on downloads.dbpedia.org
The server needs a complete overhaul and it might take a while to backup all data, then restart and migrate. It’s a multi-step process, where everything might take longer, so please have some patience.
We hope to fix it by beginning of May.
Note that the download server was very stable in the last 18 years. Around every 5 years we needed to do a week or two maintenance on it and now is that time again.
