So, this could be an ISP related issue, e.g. maybe an issue regarding peering capacities? As far as I know there have been historical issues in this direction between commerical ISPs (namely DTAG being the one I'm aware of) and educational networks such as X-WiN, so (without having any deeper knowledge on Guixes situation on this) this could apply here as well? As ci.guix.gnu.org is hosted at AS210482/the Max-Delbrueck-Centrum, I would guess that there could be something similar going on causing this, e.g. commerical ISP trying to enforce their double payed traffic strategies and the educational networks where ci.guix.gnu.org is hosted (rightfully) not participating in that/not having direct peering with these ISPs ASNs?
