Last night, Wordfence blocked a "single IP" brute force attack.
The bot continued relentlessly over 3000 times targetting the same "banned url". (a non existing login url)
My server logs clearly shows a 503 response each time.
Should I expect a "high server load" during this attack since the 503 errors are constantly being served?
On this account, I seem to be tracking high cpu usage/server loads and I am trying to determine if the issue is partly or in whole, based on this and similar attacks.
