    Just a short update on the "SSL handshake failed Error code 525" issue today. The howtoforge servers were working fine all day and were using a valid edge certificate; it seems CloudFlare messed up an update on their side, which they have now fixed. Also, not all CloudFlare proxy nodes seemed to be affected; there was always some traffic coming through, and I was sometimes able to reach the site through CloudFlare.

    Hopefully, CloudFlare has finally fixed it now for all proxy nodes, as traffic levels seem to have come back to normal.
