Too many bots on my forum

[Niiicu]

Hello,

Someone threatened me 10 minutes ago that if I don't pay him 100e in BTC, he will make my forum to fail 24/24 hours.
I told him to go away, but I see that now the forum doesn't work anymore, the page practically doesn't load.
I can see so many visitators, i think that's the problem.
How can i fix this?

Thanks,

Is IP root is the same for all guests ?

I don't know where i can check it because now my forum it's down.

Service Unavailable​

The server is temporarily busy, try again later!

Contact your host and ask them if there is any DDoS protection which can be enabled.

You do not use CloudFlare i guess ?

No, i don't have yet.

I contacted the host and they told me to add my domain on Cloudfare and to activate Under-Attack Mode on Cloudfare and after to send them a new ticket.

Hello,
I have Cloudfare now, but i also have the same problem.
It seems that Cloudfare can't block this

Did you activated under-attack mode ?

Did you activated under-attack mode ?

Yes, but is not working

Did your host change your IP? If the attacker still has it, CloudFlare doesn't matter.

They changed yesterday, it seems ok now .
