Beberapa hari ini saya merasa ada keanehan pada koneksi internet dengan memakai ISP Speedy di Tasikmalaya. Akses ke salah satu server saya di LA yang biasanya hanya 200ms, sore ini menjadi 400ms. Dan akses ke salah satu server saya di India yang biasanya 90ms, sekarang menjadi 400ms.
Ping ke server di LA

Akhirnya saya coba melakukan traceroute ke salah satu IP server di LA.

Traceroute kedua, koneksi ke gateway lebih cepat, namun koneksi keluar masih lama.

Hal ini terjadi berulang-ulang dalam waktu satu minggu ini. Koneksi ke gateway modem tidak stabil. Kadang saya merasa gateway Telkom Speedy terlalu penuh, sehingga overload, namun kadang saya merasa koneksi saya sedang diawasi.
Mungkin memang harus selalu memakai OpenVPN, walaupun untuk koneksi internet biasa.
