Manual Call Forwarding vs. Schedule-Based Call Routing: What's the Better Way to Handle On-Call Support?

Nov 17, 2025 By Ritika Bramhe In OnPage
When your team shares one support number, someone has to decide who gets the calls when customers need help after hours. And if your team rotates on-call responsibilities weekly, which is common in IT (SRE, DevOps, ITOps, etc), clinical and field engineering teams, you’ve probably relied on manual call forwarding at some point. On paper, it seems straightforward: update the forwarding number each week to point to the person who’s on call. In practice? It often turns into a scramble.

Cascading Failures Aren't Inevitable: Lessons from the AWS DNS Outage

Nov 12, 2025 By Alan Mon In Speedscale
AWS outages grab headlines because they affect millions, but the root cause often comes down to something invisible: DNS failures and cascading service dependencies. The complexity of modern cloud systems, combined with the advanced technology powering platforms like AWS, makes these outages particularly challenging to diagnose and resolve. The recent AWS outage proves one thing: you can't prevent every DNS issue, but you can create resilient architectures and prevent a single failure from taking down your entire service if you test for it.
