It seems that page must be manually updated or very slow to update. I noticed gists weren't working for what seemed like 15 minutes or more before it acknowledged there was an issue.

Even now it lists all services as available even though the top message indicates a major disruption.

We see the same. We use GitHub at such scale that we tend to see errors between 20 minutes and 2 weeks before they go up on their status page.

The status page isnt postable on HN
