Sulkowicz’s video is taken down by a DDos (Distributed Denial of service) attack, an attack that overloads the host server with connection requests. Digital Ocean:
We can confirm that there was a denial of service attack on Thursday. On Friday there was also a spike in outbound bandwidth coming from the website, likely due to a sudden increase in traffic and unrelated to the attack, so we worked with their web team to resolve the issue and their site is back up and running.
Sulkowicz also comments on her friends’ reaction to the video:
The trolls don’t upset me as much as when my friends don’t support it. I expect the trolls but to see my friends not support it [vocally] is upsetting.
