A few years ago I worked at a company that paid £30&#x2F;day for being on-call and £30&#x2F;hour (or part thereof) while investigating &#x2F; fixing incidents. We were usually on call for a week at a time with a rotation of around 6 developers.<p>We got SMS or phone call (we had a non-technical ops team that worked early&#x2F;late monitoring systems and tried to do preliminary fixes) and were expected to be available and investigate 24&#x2F;7. If you didn&#x27;t acknowledge the SMS alert within 30 minutes everyone else on the team got it, so it was in your best interest to do so to avoid waking up everyone else :)<p>Some of the services we had were pretty critical, so the fix in that case was &#x27;as long as it takes to get it working&#x27;, and then putting in a permanent fix during business hours. For lower priority services, we&#x27;d just leave it broken and fix it during business hours. If you were up fixing something in the night you weren&#x27;t expected to be in at 8am the next day.<p>In terms of escalation if there was a major problem that couldn&#x27;t be handled we&#x27;d usually get in touch with a few other people on the team to get their input. This hardly ever happened though, the only time I can remember is when the ventilation system failed in a data centre which was !FUN!<p>After that I worked at a startup that didn&#x27;t pay for any overtime or on call, which is one of the reasons why I left. Since then I&#x27;ve been contracting, so haven&#x27;t had to worry about on call but I&#x27;d be happy to do it again for the right price.
