TYB!
Hasn't been down, as far as I could see.
Probably your provider not resolving 8kun. Try changing your DNS in your network setting.
Try to avoid Google, Cloudflare etc …
Here's a small list – maybe other anons can chime in:
Alternate DNS 198.101.242.72 23.253.163.53
AdGuard DNS 176.103.130.130 176.103.130.131
DNS.WATCH 84.200.69.80 84.200.70.40
Yandex.DNS 77.88.8.8 77.88.8.1
