The recent Microsoft 365 outage should serve as a warning to households, businesses and public organisations about just how dependent everyday life has become on technology.
Email stopped working properly for many users. Microsoft Teams and other services were disrupted, leaving people unable to communicate or access information they normally take for granted.
For some, it was an inconvenience. For businesses, it could mean lost orders, delayed payments, disrupted deliveries and employees unable to carry out their work.
But the incident raises a much bigger question. What happens when the technology we rely on suddenly becomes unavailable, even for a day or two?
We have become accustomed to storing almost everything digitally. Contact details sit in mobile phones, correspondence is held in email accounts, documents are stored in cloud services and appointments are recorded in online calendars. Businesses increasingly operate through integrated systems that connect customers, suppliers, staff, banking and administration.
It is convenient and often efficient. However, it also creates a vulnerability that many people have not properly considered.
Start with something very simple: a paper contact list
One of the easiest precautions is also one of the oldest.
Every household should consider keeping a written list of important contacts, including telephone numbers and email addresses. This might include family members, friends, doctors, pharmacies, insurers, banks, utility companies and other organisations that may need to be contacted.
It is easy to assume that these details are safely stored in a mobile phone. But what happens if the phone is lost, its battery runs flat, the network fails or an online account becomes inaccessible?
A paper contact list is not dependent on electricity, an internet connection or a password.
Businesses should do the same, but on a larger scale. They should maintain an up-to-date printed directory containing contact details for employees, managers, customers, suppliers, contractors, accountants, banks and IT support.
An email address is useful, but an alternative telephone number is particularly important when email itself is unavailable.
It may seem an old-fashioned approach, but it could prove invaluable.
Households need a basic offline plan
Most people do not need an elaborate emergency plan. However, a few simple preparations can make a considerable difference.
Important appointments should be recorded somewhere other than an online calendar. Essential documents, such as insurance details, property information and important instructions, should be available offline.
Copies of important digital documents can be kept on a computer or an encrypted storage device. Particularly important information may also need a secure paper copy.
People should know how to contact family members without relying entirely on WhatsApp, Facebook Messenger or other internet-based services.
It is also sensible to keep some cash available. An internet outage does not automatically mean that card payments will fail, but payment systems can experience separate disruptions. Having an alternative is simply good preparation.
A battery-powered radio can also provide access to news and public information if internet services and television are unavailable.
The objective is not to return to the days before computers. It is to make sure that a temporary technology failure does not bring everyday life to a halt.
Businesses face a much bigger challenge
For businesses, the consequences can be more serious.
Many companies now depend on Microsoft 365, Google Workspace and other cloud-based services for almost every aspect of their operations.
Orders arrive by email, staff communicate through Teams, documents are stored in SharePoint or OneDrive, and customer information is held in online databases.
If these services become unavailable, employees may find themselves unable to do even relatively straightforward jobs.
A business might have hundreds of customer orders waiting to be processed but no accessible record of what needs to be delivered. A supplier might be waiting for confirmation of an order. An employee might need authorisation from a manager who cannot be contacted.
The business may have all its information stored safely somewhere, but that does not necessarily mean it can access or use it.
Businesses should therefore consider how they would continue operating for at least 24 to 48 hours without their normal online systems.
They should maintain offline copies of essential contact details, supplier information, delivery schedules, stock records and important operating instructions.
There should also be a simple manual procedure for recording sales, purchases, deliveries and payments until normal systems return.
This does not mean printing every business document every week. It means identifying the information that would be essential to keep the business functioning.
Backups are not the whole answer
Most organisations understand the importance of backing up their data. However, there is a difference between having a backup and being able to restore normal operations.
Storing everything in OneDrive or SharePoint is not necessarily an independent backup strategy. If access to the service is disrupted, the organisation may still be unable to retrieve the information it needs.
Businesses should maintain separate backups, including copies that are disconnected from their normal networks. They should also test whether those backups can actually be restored.
The National Cyber Security Centre provides guidance on backups, business continuity and preparing for cyber incidents. Much of that advice is equally relevant when the problem is a technical failure rather than a deliberate attack.
An organisation should also identify which operations must continue immediately, which can wait a day and which could be suspended temporarily.
That simple exercise can help managers make sensible decisions under pressure rather than trying to improvise when systems fail.
The danger of depending on too few providers
There is another issue that deserves attention.
A growing proportion of business and public administration depends on a relatively small number of major technology providers.
Microsoft, Google, Amazon and other companies provide services that underpin much of the modern digital economy. Their systems are sophisticated, extensive and generally reliable, but no technology provider can guarantee that disruption will never occur.
The problem is not necessarily that organisations use these services. For many, moving away from them would be expensive and impractical.
The problem is becoming so dependent on one provider that there is no workable alternative when it becomes unavailable.
This should concern government departments, local authorities, NHS organisations, schools and businesses of every size.
If an organisation cannot communicate with staff, suppliers or customers when its main email service fails, it has a business continuity problem that needs addressing.
The same applies to public services. People should not be left unable to obtain essential information or assistance simply because an online system is temporarily unavailable.
Try the 48-hour test
There is a straightforward way for households and businesses to discover how prepared they really are.
Imagine that tomorrow morning your email stops working, your online calendar becomes inaccessible, cloud documents cannot be opened and your usual messaging services are unavailable.
What could you still do?
Could you contact family members, employees, suppliers or customers? Could you find important telephone numbers? Could you identify the next deliveries, appointments or essential tasks? Could your business continue taking orders and recording transactions?
If the answer to most of those questions is no, there is some preparation to do.
Businesses could even conduct an annual exercise in which staff are asked to operate without email and cloud services for a few hours. It would quickly reveal weaknesses that might otherwise remain unnoticed.
Technology should make us more resilient, not less
Digital technology has brought enormous benefits. It has made communication faster, reduced paperwork and allowed even small businesses to operate in ways that would once have required much larger organisations.
But convenience can create complacency.
We have gradually discarded many of the simple arrangements that once allowed households and businesses to function when something went wrong. Telephone directories, paper records, printed schedules and alternative communication arrangements have largely disappeared.
There is no need to bring them all back. However, retaining a few basic alternatives is sensible.
The lesson from the Microsoft 365 disruption is not that we should abandon cloud computing or modern technology. It is that we should not confuse reliability with certainty.
A paper contact list, an offline copy of essential information and a simple plan for keeping things going could make the difference between a minor inconvenience and a serious disruption.
The internet has become an essential part of modern life. Perhaps it is time we reminded ourselves how to manage without it, at least for a little while.
