The most notable circumstances are DDoS attacks and terrible traffic from bots and agent waiters. Right, when we say “terrible” we don’t reliably mean someone trying to hack your site.

Do You Need Sucuri?

Generally, it is truly mass traffic that causes overage issues with your working with the provider. “Sucuri Network Blocked by Origin Firewall” This could be in the terms of visits, information move limit, etc at the day’s end, it’s “terrible” traffic since it costs you cash! Accepting that you’re using a typical working with the provider. It might, in any event, achieve your WordPress site to get suspended.

A couple examines Google of the IPs and we can see that a huge number of these are undoubtedly mediator IP addresses from Italy (which is where the Province of Arezzo is found). So almost certainly they are bots or spammers.
