Is the file manager service suspended if the domain is suspended? Okay, was it suspended because of ddos?
If a site suspends, its stuff like file manager, database management will be unavailable until it activate.
But was it suspended because of DDOS?
That’s hard to say. And it depends on what you define as a DDoS attack.
All I can see is that your website got a large number of hits on April 1st. It these hits were generated by a group of people (or group of devices controlled by one person) with the intent to take down your site, then yes, you could call it a DDoS attack. But it might also be legitimate traffic or something else.
It is not legitimate traffic, no one else really knows about my site, and it only got visited by me a few month ago.
