I was going through old BoC's related websites and I noticed that cosecha-transmisiones.com doesn't redirect to BoC's Bleep page anymore and now points nowhere, but maybe that is old news. Still, I whois'd it and it seems like the domain name was very recently (late March 2020) renewed by Warp. Even though the website was probably made exclusively for TH's ARG, why would they renew and leave it totally blank? An oversight?
I also checked on newcleardawn.com and signalquality.co.uk websites, which are known to be owned by Hexagon Sun members. Seems like both of them have their domain name expiring this year (in 9 days for signalquality). It might be interesting to see if they are renewed, even though they're not directly related to Boards of Canada, maybe it could mean that Hexagon Sun is still active in some way?
I know I'm probably not going to find anything new with this but I guess you also can't beat the boredom during lockdown
