On Thursday 12 November 2026, thousands of businesses around the world were unable to open their Outlook email or manage their Teams meetings for more than 15 hours. It was a global outage of Microsoft 365 that started in Exchange Online, the service that hosts the mailboxes, and then spread to other services. Here is what happened during the Outlook and Teams outage, whether email was lost and what your business can do when Microsoft 365 is down.
On 13 October 2026 the first year of Extended Security Updates for Windows 10ended. If your office still has computers running Windows 10, and many businesses on the Costa del Sol do, it is time to decide: pay for another year of patches, move to Windows 11 or replace the computer. We explain what has changed, what each option costs and how to decide what suits you, computer by computer.
If you run a business or are self-employed, you have probably been hearing about Verifactufor months, and the date keeps changing. The latest twist came on 5 October 2026: the Spanish Tax Agency announced it wants to postpone it again, until October 2028, to coincide with mandatory e-invoicing. We explain where the timeline stands, what is official and what is not, and what you should already check on your business computers and software to avoid surprises.
If you have a company, an office or a shop between Marbella and Estepona, you know that day-to-day work does not wait: a computer that will not start, email that stops arriving, Wi-Fi that drops in the middle of a meeting or a website that brings no clients. At Master Informática that is exactly what we do: we make your business technology work and help you sell, without you having to worry about it.
We work with freelancers, SMEs and offices across the area: Marbella, San Pedro Alcántara, Nueva Andalucía, Puerto Banús, Estepona, Casares and Manilva. Here are the services we offer and how we work.
Most breakdowns can be avoided. With regular IT maintenance we check computers, updates, antivirus and backups before anything fails. And when a problem arises, we help you remotely within minutes or come to your office in Marbella or Estepona.
If you want to know why it pays off, we explain it in preventive IT maintenance for businesses.
A well-built network is the foundation of everything else. We design and install wired and Wi-Fi networks for offices, shops and warehouses, set up servers and NAS drives for file sharing and document everything so any future change is simple. More details in our guide to office networks and Wi-Fi.
A ransomware attack or a failed disk can stop a business for days. We set up automatic backups (local and cloud), protect your computers and train your team to spot fraudulent emails. We recommend reading backups for SMEs and our practical cybersecurity guide.
Email with your own domain looks professional and keeps your messages out of spam. We set it up on all your devices, together with shared calendars and teamwork tools. We explain it in business email with your own domain.
Your website is often the first thing a client sees. We build professional websites: fast, mobile-friendly, multilingual if you work with international clients (very common on the Costa del Sol) and designed so that visitors call or write to you. You can see some of our work in our portfolio.
A good website is of little use if nobody finds it. With SEO we work so that your business appears when someone searches for your services in Marbella, Estepona or nearby: Google, your Google Maps business profile, reviews and content. And more and more customers ask artificial intelligence directly, so we also help you appear in AI search engines.
If your business repeats manual tasks every day (moving data from one place to another, preparing quotes, answering the same questions), they can probably be automated. We build small custom applications and AI solutions that save you hours of work.
If you are looking for a trusted IT company in Marbella, Estepona or anywhere on the western Costa del Sol, tell us what you need. We will advise you with no obligation.

This week the tech world is talking about nothing else: PHP2Shell. It is the name given to two critical vulnerabilities in PHP, the language that powers most of the world's websites, including every site built with WordPress, WooCommerce, PrestaShop or Joomla. Spanish media such as El Mundo describe it as a flaw that threatens seven in ten websites. We explain what it is, whether your website is at risk and what needs to be done.
More…You open your website and, instead of your page, a blank message appears: "There has been a critical error on this website". No menu, no content, no contact form. For any business it is an emergency: every hour the website is down means customers going to the competition. This week it happened to one of our clients, and we explain what happened, how we solved it in minutes and what you can do to prevent it.
More…Wi-Fi that drops in the meeting room, the printer that "disappears" from the network or the video call that freezes just as you are talking to a client. Network problems are among the most common issues in offices in Benalmádena, Marbella and the Costa del Sol, and they almost always have the same cause: a network that grew through patches and that nobody designed around how the business works today.
More…Receiving a quote from an address like "companyname@gmail.com" or "info@yourcompany.es" does not convey the same thing. Email with your own domain is one of the simplest improvements to a business's image, and it also brings practical advantages in security, organisation and control that many SMEs in Benalmádena, Marbella and the Costa del Sol still miss out on.
More…A hard drive that will not boot, a USB stick the computer no longer recognises or a memory card that asks to be "formatted" are among the most stressful faults, because what is at stake is not the device but the documents, photos or company accounts. The good news is that in many cases the data can be recovered. The bad news is that the first minutes after the failure are decisive and one wrong step can lose it forever.
More…Many small businesses in Benalmádena, Marbella and the rest of the Costa del Sol think cyberattacks are something that happens to big companies. The reality is the opposite: SMEs are the favourite target because they usually have less protection and a single slip is enough to paralyse the office for days. At Master Informática we have been supporting local businesses for more than 20 years, and these are the risks we see most and how to prevent them without making your life complicated.
