We are currently experiencing som fairly serious problems with @wdscholia . There seems to be a bad bot operating on https://scholia.toolforge.org/ even though our robots.txt should prohibit it. It might be this that hinders a good connection to the SPARQL endpoint. Or perhaps it is just because most of our queries are to the legacy endpoint?

@fnielsen @wdscholia yea, I actually may have fell for this myself :(
