Vega Scanner Took Website offline?

I used the Subgraph Vega scanner to scan a website, I wanted to get any linked social media pages from their site. Anyway soon into the scan the page went offline with a 404. I checked with different connections from different IPs, my phone and another WIFI, but the website was definitely down. Was this a fault of the scans? The site is back up now.

Thanks for any help,
