My site uses Netlify to host and Cloudflare for DNS. On Monday, my website started throwing 522 and 521 errors, and after a few hours, showed a 404. Shortly after that, my homepage was replaced by a random screen – still not sure what it is. (See screenshot below). It says “UISP” and asks you to log in with a local account.
I went into Cloudflare and deleted all the DNS records, and re-added them, replacing the existing A records from Netlify with flattened CNAME records. When I did this, the site started working fine again.
Now the site is back up again, but I’m still not sure what happened, and what this screen was? I was getting nervous and wondering if I’d been hacked or something!
Does anyone have any ideas what might have happened here?
Thanks for the help in advance!
