I was not aware of the attacks going on until this happened:

1. Tried to download "Unknown Horizons" (game featured recently on Hacker News) binary, github-link doesn't work.

2. Think "Ok, might be an old link", google their github-repository, github appears down.

3. Try accessing github status website, is down.

4. Interested, try to visit github status twitter account, twitter is down.

Really weird experience, normally at least the second source of news on a downed website I try during an attack works.
