Hi!
I have made some efforts to collect mostly last of working Gnutella and Gnutella2 caches I could find openly and added it on my website, also created some caches myself. Also tried my best to recreate the original Gnutella web cache scan report so can always get a status in real time of the remaining working caches. Isn’t 100% perfect yet but works at least and will be improved further on! Hope this can help preserve what’s left and probably build something in the future so isn’t dying out instantly or disappear totally.
