Do we have logs that would allow us to know more about it?

What we know:

• More then 15 people logged in at the same time.
• Report that updating nodes was slow.
• On 17:14(israel time) site down reported.
• Alon checked on 17:54 and site was online.

Closed until we have a more concrete evidence for this.
