IT Emergency Support: What to Do When Your Business Systems Go Down

Your server just crashed. Email is down. Staff can't work. The clock is ticking and every minute costs money. IT emergency support is about getting your business back online as fast as possible. Here's exactly what to do — and what NOT to do — when disaster strikes.

Step 1: Don't Panic — Assess the Situation

Before calling anyone, take 2 minutes to understand what's happening:

• Is it just one computer or the whole office? — A single PC issue is very different from a network-wide outage
• Did something change recently? — Windows update, new software installed, load shedding?
• What error messages are showing? — Take a photo of any error screens
• Is the internet working? — Check on your phone using mobile data as a comparison

Step 2: Common IT Emergencies and Quick Fixes

Server Down After Load Shedding

This is the #1 IT emergency in South Africa. When power returns after load shedding, servers may not restart properly. Do NOT keep restarting the server — this can corrupt data. Call for remote IT support immediately.

Ransomware Attack

If you see a ransom message on your screen: disconnect from the network immediately. Unplug the ethernet cable or turn off Wi-Fi. Do NOT pay the ransom. Call a cybersecurity specialist right away. Time is critical — the faster you isolate the infected machine, the less damage it can do.

Email System Down

If nobody in the office can send or receive email, check if Microsoft 365 has a service outage (status.office.com). If the service is fine, the issue is likely with your DNS or email configuration. This needs IT support to resolve — don't try changing settings yourself.

Network Failure

If nobody can access the internet or shared files, restart your router and main network switch (unplug for 30 seconds, plug back in). If that doesn't work within 5 minutes, contact your IT company — it could be a switch failure, firewall issue, or ISP problem.

Step 3: Call for Emergency IT Support

When you call for IT emergency support, have this information ready to speed things up:

1. What's affected — one PC, the server, the whole network?
2. When did it start — exact time if possible
3. What happened before the issue — load shedding, update, suspicious email?
4. How many staff are affected and can't work
5. Any error messages (photos are best)

What NOT to Do During an IT Emergency

• Don't restart servers repeatedly — this can cause data corruption
• Don't try to fix it yourself if you're not sure — well-meaning attempts often make things worse
• Don't pay ransomware — there's no guarantee you'll get your data back
• Don't delete suspicious files — they may be needed for forensics
• Don't ignore the warning signs — if things have been "slow" for weeks, a crash was coming

Preventing IT Emergencies: The Proactive Approach

The best IT emergency support is preventing emergencies in the first place. Businesses with managed IT support experience 85% fewer critical incidents because:

• 24/7 monitoring catches problems before they become emergencies
• Regular maintenance keeps systems healthy
• Automated backups mean data is always recoverable
• Cybersecurity tools block threats before they cause damage
• UPS monitoring ensures graceful shutdowns during load shedding
