Masalah seperti WiFi putus-putus, aplikasi error, browser lemot sering dikira berasal dari jaringan.
Namun secara sistemik, penyebab utama justru berasal dari storage pressure (low free space condition) yang mempengaruhi OS networking layer.
💡 Core Finding: Saat storage di bawah 10–15% free space, OS gagal membuat temporary buffer untuk DNS, TLS handshake, dan cache networking.

📡 5. DNS Failure Cascade Analysis
DNS failure terjadi ketika:
Temporary file tidak bisa dibuat
Cache resolver tidak tersimpan
Query retry loop terjadi
DNS Error
Penyebab Umum
DNS_PROBE_FINISHED_NO_INTERNET
cache write failure
ERR_NAME_NOT_RESOLVED
resolver timeout
SSL handshake failure
temp cert storage error
📱 6. App Behavior Under Low Storage
Aplikasi

📌 9. Key Insight Engineering
Masalah jaringan modern tidak lagi hanya pada sinyal, tetapi pada:
OS resource allocation failure
Storage write bottleneck
DNS cache dependency
Background process starvation
💡 Kesimpulan: 1 dari 3 kasus “internet error” sebenarnya adalah storage issue, bukan jaringan.
