We'd like to keep Trello up 100% of the time. When that doesn't happen, we write about it here.

Monitoring - After looking at the timing of incidents we suspect a change in our websocket services may be having an unexpected detrimental side effect on CDN edge nodes that intermittently messes with incoming requests causing Trello to be unreachable for a small percentage of users. While our CDN continues to investigate things on their end we have rolled back the change and are monitoring the results.

Investigating - Some users may see an "Site not available" error when trying to access Trello. This is impacting small groups of users in specific geographic areas: mainly Brazil, Serbia, and the UK.

We are looking into this with our CDN provider.
