Frequently asked questions

IT emergencies include complete server outages, ransomware attacks, critical application failures, loss of internet connectivity, and anything preventing your business from operating. Speedster IT offers same-day emergency response — typically within 2–4 hours for on-site attendance in London and remotely within 30 minutes.

Yes. Emergency IT support is available 24 hours a day, 7 days a week, including bank holidays. Out-of-hours incidents are handled by our on-call engineers. Call rates may apply for non-contract customers — contact us for details.

Yes. Speedster IT provides ad hoc emergency call-out support for businesses without a managed service contract, billed at an hourly rate. However, contracted customers receive priority response times and lower rates. We recommend at minimum a monitoring contract so we identify issues before they become emergencies.

Immediately disconnect affected machines from the network (unplug ethernet, disable Wi-Fi) to stop the spread. Do not turn machines off — forensic evidence may be lost. Then call Speedster IT on 020 4511 9111. Do not pay any ransom without taking professional advice first. We will assess the extent of the infection, contain it, and begin recovery from clean backups.

If your network is completely down, our engineers can attend on-site or connect via a 4G hotspot on an unaffected device. We carry spare networking hardware to most emergency call-outs. Our remote access tools operate independently of your network where possible, giving us options even in severe outages.
