Hi Point4d, Specifically, from the thread linked by Evgeny:
"At the MDC level there’s an unrelated recent ban of some Russian IP ranges in place due to massively increased port scans and intrusion attempts since about one week. I hope you can use the Chinese mirror for the time being." That mirror is at https://mirrors.sjtug.sjtu.edu.cn/guix . Let us know if it works. Kind regards, T G-R Sent on the go. Excuse or enjoy my brevity.
