Everything from Microsoft to Outlook came to a halt! Why do the world’s biggest cloud servers cheat so often?

Are you having trouble doing office work this morning? Mails not opening on Outlook, meetings not happening on Microsoft Teams? If the answer is yes, then this is not just happening to you. The problem is not with your device or network, but a major flaw with tech giant Microsoft. This led to a sudden Microsoft outage on Friday that affected service around the world. A technical glitch at Microsoft has affected services ranging from Outlook to Microsoft 365, Teams and OneDrive.

Even a small technical glitch in the cloud service of a major tech company like Microsoft can affect the work of millions of users. Many times, it’s not the server’s fault, but a fault in the network, software update, or login system that causes the problem. This is the reason why users face simultaneous issues on multiple services from Outlook to Teams and Azure. But the question is why the service of a company like Microsoft fails so often? Is it just a server problem or are there some vulnerabilities in the cloud system due to which a small mistake can put users around the world in trouble? Let’s understand the 7 major reasons behind cloud outages.

1. Misconfiguration can corrupt the system

Oftentimes the cause of a service problem is simply a wrong setting. Large companies manage thousands of servers through automated systems. Engineers make even a small change and it reaches many services. If there is a mistake in the settings, the impact is also seen on a large scale. Companies try to fix the problem by reverting to old settings, but this takes time.

2. Hidden bugs in software updates

Companies like Microsoft constantly bring new updates and features to their software to improve the user experience. But many times any minor technical glitch present in the update does not come to light during testing. The real problem comes to light when millions of people start using that service simultaneously. To avoid this, companies first apply the update to some servers. Only when everything is correct is it transmitted to the rest of the system.

3. Website not opening due to DNS problem

DNS is called the phone book of the Internet world. When a user tries to open a website such as Outlook.com, DNS tells the computer where the website’s server is located. If there is a fault in the DNS then the website does not open even after starting the server. Wrong setting, excessive traffic or DNS server failure can cause this. Many times, even after the issue is fixed, some users may face issues due to outdated data.

4. Problem with Entra ID and login failure

Microsoft Entra ID is a company identity and login related service. Previously it was called Azure Active Directory. The role of Entra ID is very special for logging into services like Outlook, Teams and SharePoint. If there is a problem with this, users cannot login even after entering the correct password. Many users believe this problem is due to Microsoft service stopping altogether, while they are unable to understand the real problem.

5. Problem in data center

Whether it’s Microsoft’s cloud service or any other service, some things are essential for everyone. For example, large data centers are designed for cloud services, where thousands of servers work continuously 24 hours a day. These servers require electricity to run and a cooling system to keep them cool. If the power supply is affected, the backup generator fails or there is a problem with the cooling system, there is a risk of service interruption. Microsoft is making preparations for data centers and backups in various locations, but major technical glitches are affecting users and services.

6. Network disruption and DDoS attacks

Many times the server is fine, but users cannot access it due to network issues. Many networks are interconnected to send data from one place to another on the Internet. If there is a problem in their path, the connection may break. Also DDoS attacks add to the problem. In this, pressure is created on the service by sending a large number of fake requests simultaneously. The result is that the end users start facing problems in using the website or application.

7. Dependency of multiple services on one system

Many services of cloud companies are interconnected. For example, different applications may use the same storage, database, or login system. In such a situation, if there is a problem in one of the mixed systems, many services are affected simultaneously. This is called cascading failure. Even after the problem is resolved, the problem may escalate as millions of devices try to reconnect simultaneously.

Why is backup important for companies?

Cloud technology has made the work of tech companies easier, but has also increased the risk of outages. Therefore, it is important that companies back up their data and do not depend entirely on any one platform. If necessary, other data centers or other cloud services can be used.
