Summer is a period when many companies experience slower activity, employee vacations, and a temporary reduction in workload. This makes it an ideal time to take care of IT activities that are often postponed during the rest of the year because they require planning, maintenance windows, or temporary service interruptions.
Scheduling IT maintenance during the summer period allows companies to return to full operations with more secure, updated, and reliable systems, reducing the risk of problems occurring precisely when business activity resumes at full capacity.
Why Take Advantage of the Summer Period for IT Maintenance?
During normal business operations, working on servers, networks, and devices can be complicated. Even a short interruption can disrupt employees and slow down daily activities.
During the holiday period, however, fewer employees are generally present and system workloads may be lower.
This makes it possible to schedule activities such as:
- Server updates
- Replacement of outdated hardware
- Network maintenance
- Backup verification
- Security system updates
- Infrastructure cleanup
- Software license reviews
The goal is not simply to “fix the computers,” but to prepare the IT infrastructure for the next business period.
Update Operating Systems and Software
One of the most important maintenance activities involves updates.
Operating systems, applications, firmware, and network devices should be kept up to date to fix vulnerabilities, improve stability, and ensure compatibility with newer technologies.
Before employees return, it is therefore advisable to check:
- Company computers
- Physical and virtual servers
- Firewalls
- Switches
- Access points
- Business applications
- Backup systems
- Device firmware
A structured patch management process helps prevent outdated devices from becoming weak points in the overall infrastructure.
Check Your Backups
A backup that has never been tested cannot be considered a reliable guarantee.
The summer period can be used to verify that:
- Backups are running correctly
- Data can actually be recovered
- Multiple copies of critical data exist
- Backup copies are protected from unauthorized access
- Critical backups are isolated or immutable
It is also important to perform restore tests, simulating the recovery of files, databases, or entire systems.
This makes it possible to identify potential problems before an actual emergency occurs.
Check Servers and Network Infrastructure
Servers and network equipment often operate continuously throughout the year. A scheduled inspection can help identify components that are beginning to show signs of wear.
It is advisable to check:
- Disk health
- Temperatures
- Power supplies
- Fans
- Resource utilization
- Available storage space
- System logs
- UPS status
The network should also undergo a general review, including switches, firewalls, access points, and cabling.
Organize the Corporate Network
Over the years, a corporate network can become increasingly difficult to manage.
Unused devices, outdated configurations, old VLANs, forgotten accounts, and equipment that is no longer monitored can accumulate.
Summer maintenance can be an opportunity to carry out a complete infrastructure cleanup.
Useful activities include:
- Updating network documentation
- Reviewing VLANs
- Removing obsolete configurations
- Checking connected devices
- Removing unused equipment
- Reviewing administrative access
A well-documented and organized network is much easier to manage and secure.
Check Company Computers and Devices
Devices used by employees every day also deserve attention.
For each computer, it can be useful to check:
- Hardware condition
- Available storage
- Software updates
- Antivirus and endpoint protection
- Drive health
- Installed software
- Battery condition on laptops
This is also a good opportunity to identify devices approaching the end of their lifecycle and plan their replacement.
Review User Accounts and Permissions
Another important maintenance activity involves access to company systems.
Throughout the year, new accounts may be created, roles may change, or employees and contractors may leave the organization. If these changes are not managed correctly, unnecessary accounts and permissions may remain active.
It is therefore advisable to review:
- User accounts
- Administrative accounts
- VPN access
- Folder permissions
- Cloud service access
- Former employee and contractor accounts
The principle should be simple: every user should have only the access necessary to perform their job.
Review Cybersecurity
Summer can also be the right time to perform a general cybersecurity review.
Companies can verify the configuration of:
- Firewalls
- Antivirus solutions
- EDR systems
- Multi-factor authentication
- VPNs
- Monitoring systems
- Anti-spam filters
- Email security solutions
Periodic reviews make it possible to identify outdated configurations or security measures that are no longer appropriate for the company’s needs.
Review Licenses and Contracts
IT maintenance is not limited to hardware.
Before employees return, it is also useful to review software licenses, warranties, and support contracts.
A review can identify:
- Licenses approaching expiration
- Software that is no longer being used
- Duplicate services
- Warranties nearing expiration
- Maintenance contracts that need to be renewed
This helps prevent service interruptions while also eliminating unnecessary expenses.
Schedule Maintenance Without Disrupting Operations
Maintenance must be carefully planned.
Not all activities can be performed simultaneously, and some may require servers or network equipment to be restarted.
It is therefore important to establish:
- Which activities have priority
- Which systems will be affected
- How long each intervention is expected to take
- Which services may be temporarily unavailable
- Which recovery procedures should be followed if problems occur
Good planning significantly reduces the risk of a maintenance operation turning into an operational problem.
Prepare for Employees’ Return
Maintenance should not end the day before employees return to the office.
Before operations resume, it is advisable to verify that all critical systems are working properly and that employees can access their resources normally.
A final check should include:
- Network connectivity
- Access to servers and applications
- VPN
- Printers
- Cloud services
- Authentication systems
- Backups
This allows any issues to be resolved before business activity returns to full capacity.
A Summer IT Maintenance Checklist
A simple checklist can help ensure that the most important activities are not overlooked:
- Updates: operating systems, software, and firmware.
- Backups: process verification and restore testing.
- Servers: hardware, storage, and performance checks.
- Network: switches, firewalls, access points, and VLANs.
- Security: antivirus, MFA, VPNs, and monitoring systems.
- Devices: PCs, laptops, and peripheral equipment.
- Accounts: user accounts and privilege reviews.
- Licenses: expiration dates and usage.
- Hardware: identification of outdated equipment.
- Documentation: updated network diagrams and configurations.
An Investment for a Smooth Return to Work
Summer IT maintenance should not simply be viewed as a collection of technical tasks to perform while employees are away.
It is an opportunity to evaluate the condition of the entire infrastructure, address issues that have accumulated throughout the year, and plan future investments.
Returning to work with updated systems, verified backups, efficient devices, and a properly configured network reduces the risk of interruptions and allows employees to resume their activities immediately.
Proper IT maintenance planning can therefore transform the summer period from a simple operational slowdown into a valuable opportunity to make the company more secure, efficient, and ready to face the months ahead.
