Perhaps we should mirror the entire site (it seems to be plain good old HTML) and archive it on IPFS or so to get rid of these dumb geoblocks.
There's also the following copy on the same page:
"Repeated, crippling DDoS attacks from the following countries has caused me to block their access. Apologies to the innocent.
Brazil, Singapore, Angola, Seychelles, UAE."
My guess is that the geolocation Gods placed GP in Singapore.
