Amir writes about uptime monitoring, network diagnostics, SSL/TLS, alerting strategy, and incident response. With a background in site reliability and network operations, Amir focuses on what it actually takes to keep web services reachable: synthetic checks that catch real failures, alert routing that respects on-call schedules, certificate management that prevents expiry outages, and the network-layer fundamentals — DNS, HTTP, TCP, ICMP — that underpin every reliable service.
