Just in case you didn't trust your photos/albums/comments with Facebook (or Google), you could try a privacy respecting, user-owned, self-hosted solution (self-hosting coming soon):
Are you talking about the certificate problem or a DNS error. If its a certificate problem, its because each user in our system generates their own self-signed certificates. If it was an actual error - Some windows/DNS servers query "AAAA" records currently which gets our DNS server code in trouble - hopefully we can fix this soon.
