We already had the patch in place before news of the bug went public.
How had you managed to find out about the bug before the news hit the front pages? From what I know even big corporations like Yahoo were not aware.
It was just coincidence. We happened to be updating our front end before the announcement and OpenSSL showed up as needing an update. Cloudflare claims to have known in advance, though it seems they weren't fully patched yet until a little while after the announcement.
