I'm guessing Cloudflare flagged the Pelican forums for some reason.

I was going to post that it was probably DNS related. Glad you got it sorted.

FYI, I think it's good to not keep all of your DNS eggs in one basket (cloudflare).

There's nothing wrong with cloud flare, I used them, but in addition, you may want to include a couple of other vendors at the bottom of the list to ensure that you are always likely to get something back.

Lots of good info on good options here.

I think I've got about 5-8 DNS servers in my list (Windows and Mac) google, cloudflare, pi-hole, OpenDNS and local ISP.

Google

Default upstream DNS provider on the Pi-hole.

8.8.8.8
8.8.4.4


OpenDNS Home (owned by Cisco)

Built-in features include a phishing filter, this is the OpenDNS version the Pi-hole would use if you select it during setup.

208.67.222.222
208.67.220.220
208.67.222.220
208.67.220.222
2620:119:35::35 (IPv6)
2620:119:53::53 (IPv6)



OpenDNS also provides the OpenDNS FamilyShield (free)- option. The service blocks pornographic content, including our “Pornography,” “Tasteless,” and “Sexuality” categories, in addition to proxies and anonymizers (which can render filtering useless). It also blocks phishing and some malware.

208.67.222.123
208.67.220.123


Level3 DNS

This DNS service does no filtering of itself, but redirects mistyped URL to Level 3 Web Search.

Comodo Secure DNS

SecureDNS references a real-time block list (RBL) of harmful websites (i.e. phishing sites, malware sites, spyware sites, and parked domains that may contain excessive advertising including pop-up and/or pop-under advertisements, etc.) and will warn you whenever you attempt to access a site containing potentially threatening content.

8.26.56.26
8.20.247.20
