As the security system activated, it began blocking all traffic to the site to prevent losses.
Losses of data, or losses of bandwidth? If it was a DDOS, no data should be lost.
To me, this looks like a DDoS attack caused increased traffic and exceeded the maximum quota it receives from hosting. I am unsure if removing the suspension will be possible if the bandwidth limit is not increased.
joker_josue have you talked to the hosting support, maybe at least this month you should pay for a bigger hosting package, and later go back to a smaller one if it is enough. I assume that btt members can help with a donation to compensate for any extra payment.
