Just a quick share for when other people would notice/bring this up :
The Getty services have been going on and off for some time, but are currently down almost 48h.
Gregg@Getty reacted on my report:
The Getty Vocabularies LOD site (vocab.getty.edu) has been experiencing traffic volume that amounts to a "Denial of Service" attack for many weeks now. Our cloud server administrators are looking at options for implementing rate limiting, but no solution has been put in place yet.
More information will be forthcoming over the next few months on the complete overhaul of the services offered by the Getty Vocabularies. Thank you for your continued patience and interest in the Getty Vocabularies.
