    Perjelas dulu, anda pakai apa (shared-hosting, VPS, Dedi). Juga webserver yang dipakai (apache, nginx atau yang lain).

    Dari info apa anda 'tahu' kalau terserang DDOS?.

    Belum tentu kena DDOS. Bisa jadi bot seperti googlebot yang sedang 'berkunjung'.

    Kunjungan nambah 20x lipat kayaknya bukan DDOS... Kalaupun niat DDOS kurang banyak itu. Hehehe. Tujuan utama DDOS kan server Anda down. Kalau masih bisa diakses dengan lancar sih aman2 aja menurut saya.

    Yg paling bawah itu IP local server anda sendiri. Saya beberapa kali menemui kasus server kena hack lalu melakukan DDOS dari dalam ke luar, biasanya flooding paket UDP. Tujuannya biar network penuh.

    masih bisa jalan Tuan, cuman berat, karena cpu nya sering 100% ne. yg saya bingungkan cuman ini cpu nya kenapa penuh terus. kalau google bot harus nya tidak sampai segitu nya. udah saya reboot . tapi beberapa saat kemudian gitu lagi.

    oke terimakasih Tuan, semoga aja bemoga cuman botgoogle.

    Coba cek nginx access log nya supaya tahu siapa yang sedang akses website... (jika diduga kebanyakan kunjungan ke website).

    Load server tinggi bukan karena banyak yang akses saja. Bisa jadi script phpnya yg tidak efisien, database, dll.
