I use Slack daily. It works perfectly fine. Outages<\/a> rarely happen. Even if they happen, they are resolved quickly. And this is the same for many other tools.<\/p>\n\n\n\n

But how are they all doing it\u2014keeping services running and resolving issues quickly?<\/p>\n\n\n\n

Their secret lies in On-Call Schedules.<\/p>\n\n\n\n

On-call schedules make sure someone is always available to handle emergencies, so your systems stay reliable.<\/strong><\/p>\n\n\n\n

Whether you run a small startup or a big company, understanding on-call schedules can save you from sleepless nights and angry customers.<\/p>\n\n\n\n

This article covers everything you need to know about on-call schedules: What they are, why they\u2019re important, and how to set up one. Plus, you get ready-to-use on-call templates as bonus.<\/p>\n\n\n\n

What is an On-Call Schedule?<\/h2>\n\n\n\n

An on-call schedule tells you who will handle incidents<\/a> when they happen. It’s a plan that rotates team members so everyone takes turns being the first responder<\/a>.<\/strong><\/p>\n\n\n\n

The main purpose of on-call schedules is to make sure someone is always available to tackle issues fast.<\/strong><\/p>\n\n\n\n

When you’re on-call, your responsibility is to respond to the alerts immediately, look into the issue, fix it if you can, or call in others for help.<\/p>\n\n\n\n

\n\n\n\n

Example of an On-Call Schedule<\/h2>\n\n\n\n

Let’s say you have a team of four engineers: Alex, Ben, Chris, and Dana. Your weekly on-call calendar might look like this:<\/p>\n\n\n\n

Week 1: <\/strong>Alex is on-call<\/p>\n\n\n\n

Week 2:<\/strong> Ben is on-call<\/p>\n\n\n\n

Week 3:<\/strong> Chris is on-call<\/p>\n\n\n\n

Week 4:<\/strong> Dana is on-call<\/p>\n\n\n\n

After Dana\u2019s week, the cycle starts over with Alex again. This simple weekly rotation makes sure everyone shares the on-call load fairly.<\/p>\n\n\n\n

We, at Spike<\/a>, also follow a weekly rotation. Here\u2019s how our on-call schedule looks:<\/p>\n\n\n\n

Why Do You Need an On-Call Schedule?<\/h2>\n\n\n\n

Atlassian\u2019s major outage in 2022<\/a>\u2014caused by a faulty migration script and compounded by communication issues\u2014resulted in a nearly 20% drop in share price and loss of customer trust.<\/p>\n\n\n\n

While Atlassian did have on-call schedules, the incident highlights how quickly things can spiral when the response is slow or misdirected.<\/p>\n\n\n\n

Now, imagine the plight of companies without any on-call coverage. It\u2019s a nightmare! Teams scramble, customers get angry, and revenue is lost.<\/p>\n\n\n\n

However, with an on-call schedule in place, you can<\/p>\n\n\n\n
