Saya rasa ini bukan masalah di rumah saya. Tolong review balasan saya
berkut ini.

Dari sisi ICMP memang sebagian besar dapat reply, tapi kebanyakan
masalah ini hanya berdampak pada protocol HTTPS. Sedangkan via HTTP bisa
diakses.

Ketika saya menulis laporan via email kemarin malam, semua situs di
bawah ini tidak bisa diakses via HTTPS, namun via HTTP bisa.

(Sekarang *sebagian* dari list ini *sudah bisa* diakses via HTTPS)

- https://superuser.com 
- https://math.stackexchange.com
- https://freedns.afraid.org
- https://avatars.githubusercontent.com
- https://bri.co.id
- https://www.digicert.com
- https://www.trustico.com
- https://www.nytimes.com
- https://www.bloomberg.com
- https://www.allsides.com
- https://news.yahoo.com
- https://yahoo.com
- https://americanfootballdatabase.fandom.com
- https://www.cnn.com

Masalah tersebut kadang muncul kadang hilang.

Sejauh ini yang paling parah adalah akses ke bank BCA. Semua layanannya
sama sekali tidak bisa diakses. Apakah dari Biznet memang memblokir
akses ke bank BCA?

Mulai dari mobile app hingga web banking semuanya tidak bisa diakses
dari jaringan Biznet. Masalah yang sama juga dialami oleh pelanggan
Biznet lainnya (Michael William J.) di CC list.

Akses internet banking BCA via HTTP (gagal):

root@integral2:~# curl -v http://ibank.klikbca.com
*   Trying 202.6.208.9:80...
* Connected to ibank.klikbca.com (202.6.208.9) port 80 (#0)
> GET / HTTP/1.1
> Host: ibank.klikbca.com
> User-Agent: curl/7.81.0
> Accept: */*
> 
* Recv failure: Connection reset by peer
* Closing connection 0
curl: (56) Recv failure: Connection reset by peer

^ Connection reset???

Akses internet banking BCA via HTTPS (gagal):

root@integral2:~# curl -v https://ibank.klikbca.com
*   Trying 202.6.208.9:443...
* Connected to ibank.klikbca.com (202.6.208.9) port 443 (#0)
* ALPN, offering h2
* ALPN, offering http/1.1
*  CAfile: /etc/ssl/certs/ca-certificates.crt
*  CApath: /etc/ssl/certs
* TLSv1.0 (OUT), TLS header, Certificate Status (22):
* TLSv1.3 (OUT), TLS handshake, Client hello (1):

^ Stuck di TLS handshake dan akan berakhir timeout.

Sebagian besar masalah HTTPS selalu berhenti di TLS handshake. Walaupun
tidak semua situs bermasalah via HTTPS, tapi banyak yang bermasalah.

> Terima kasih atas perhatian dan kerja samanya.

Terima kasih sudah merespon. Mohon pertimbangannya lagi, saya rasa ini
masalah di jaringan Biznet, bukan misconfiguration di rumah saya.
