School broadband: capacity, resilience and renewal

Start with the work the connection must support

A broadband purchase begins with a timetable and a list of dependencies. Record when whole classes sign in, staff upload assessment evidence, cloud backups run, parents contact the office and internet telephones are busiest. A connection that feels fast on an empty afternoon may still struggle during the first lesson. Measure actual utilisation, upload demand, delays and outages before specifying an upgrade.

Ask IT support to separate internet problems from local network problems. If a wired computer performs well but a classroom trolley does not, the bottleneck may be wireless coverage, authentication or an overloaded access point. Increasing the broadband speed will not necessarily fix it. Our school Wi-Fi guide explains that part of the investigation.

For schools and colleges in England, the Department for Education's broadband standard recommends full fibre and resilient connectivity. It sets different capacity expectations for primary settings and for secondary, all-through and further education settings. Check the current standard against your type of setting; these are not interchangeable purchasing specifications for every UK school.

Compare the complete service

Request a written schedule that separates connection capacity, expected performance, support and repair commitments. Marketing descriptions such as business broadband say little about what happens during a school-day outage.

Decision	What to establish
Capacity	Download and upload performance, contention and upgrade options
Installation	Survey requirements, landlord permission, construction and realistic lead time
Repair	Support hours, response target, restoration commitment and exclusions
Network services	Firewall, filtering, public addresses and responsibility for configuration
Commercial terms	Start date, minimum term, price changes, notice period and exit costs
Resilience	Backup route, automatic failover, power protection and testing

An advertised response time is not the same as a restoration time. Ask who owns a fault when the connection, router and filtering service come from different organisations. There should be a clear route for the school to raise one incident without repeatedly proving which supplier is responsible.

Design the backup as a working service

Write down which activities must continue during an outage. The office may need attendance information, safeguarding contacts and telephone access before classrooms need video streaming. Establish whether the backup has enough capacity for those priorities and whether traffic can be managed appropriately.

Check independence as well as speed. Two services can share an underlying duct, exchange dependency, power source or piece of equipment. Ask suppliers to explain the main common failure points without assuming that different brand names mean different infrastructure. Include any mobile or satellite constraints relevant to the site.

The backup must preserve the school's security and safeguarding arrangements. An unfiltered personal hotspot is not an adequate substitute for a planned school connection. Test filtering, monitoring coverage, telephone behaviour and access to critical systems while the backup is actually carrying traffic. Record who can authorise emergency changes.

Prepare the cutover

Build a short implementation plan with a named school decision maker and technical lead. Include firewall rules, remote access, telephone services, fixed public addresses, website dependencies and any suppliers that restrict access to known addresses. Agree how the school will communicate if the usual email or telephone service is unavailable.

Keep the existing service until the new one has passed agreed acceptance checks and the contractual position permits an overlap. Schedule disruptive work around teaching, examinations and reporting deadlines. A project is not complete when an installer shows a speed test; it is complete when the school can perform its important tasks safely.

Suggested acceptance checks include a full-class login, a large upload, a call during heavy network use, a filtering check, controlled failover and recovery to the primary connection. Repeat checks in more than one part of the building so a local wireless problem is not mistaken for a circuit fault.

Make renewal evidence easy to find

Keep a one-page service record with circuit identifiers, support contacts, renewal dates, costs and the location of technical documentation. Record meaningful incidents and their effect on lessons or administration. Review this before the notice deadline rather than waiting for the final bill.

Use that evidence to decide whether the next investment should be capacity, resilience, support or the internal network. The best connection is one whose performance and recovery arrangements match the school's actual needs, with responsibilities that remain understandable when staff or suppliers change.
