For decades, regional internet service providers have competed almost exclusively on bandwidth, uptime, and price. But a series of seismic shifts from Microsoft and the world’s largest cloud vendors are quietly redrawing the competitive map — and opening a window of opportunity that forward-thinking ISPs cannot afford to ignore.
Underestimating What It Actually Takes to Run a Subscription Business
On 14 October 2025, Microsoft ended support for Windows 10, the world’s most widely deployed operating system. At the time of its retirement, Windows 10 still accounted for roughly 40.5% of all Windows installations globally. That is not a footnote — it is a vast, largely unmanaged installed base suddenly exposed to security vulnerabilities, with no patches coming and no safety net in place. (Redmond Magazine, 2025)
But Windows 10 is only the headline act. The EOL cascade runs deeper. Office 2016 and 2019 ended support on the same day. Exchange Server 2016 and 2019 followed. Skype for Business Server 2015 and 2019 were retired, pushing organisations toward Microsoft Teams. SharePoint Server 2016 and 2019 will reach end of support in July 2026. SQL Server 2016 follows in the same month. Office LTSC 2021 expires in October 2026. Dynamics GP and NAV 2016 end in April 2026. This is not a single migration event — it is a rolling technology cliff that will define enterprise IT budgets for the next two to three years. (4sysops, 2026)|
Analyst firm Omdia has called this the PC industry’s largest device refresh opportunity in years. For enterprises and SMBs with dedicated IT departments, it is a manageable — if painful — transition. For the millions of small businesses that have no IT staff at all, it is bewildering. These are precisely the customers that regional ISPs already bill every month, already have a trusted relationship with, and are uniquely positioned to serve. (Omdia, 2025)
The Vendor Lock-In Wake-Up Call
If the EOL wave is a slow-moving opportunity, the Microsoft-Nayara Energy incident was a sudden one. In July 2025, Microsoft abruptly cut off all cloud services to Indian energy giant Nayara Energy without notice — blocking access not just to software, but to the company’s own data and proprietary tools, despite fully paid licences. The action was driven by EU sanctions pressure related to Russia, and the abruptness was apparently intentional: a punitive message to the market. (CIO, 2025)
The incident crystallised a risk that CIOs had largely theorised about but never had to confront: a major cloud vendor can, and will, terminate services instantly when geopolitical or regulatory pressure demands it. As defence evangelist Roger Grimes of KnowBe4 put it, cloud means someone else’s computer. Attorney Cameron Powell went further, recommending that enterprises consider local providers and open-source alternatives to reduce exposure to exactly this kind of unilateral action. (CIO, 2025)
This is not an isolated concern. Research from the Bitkom Cloud Report 2025 found that 82% of companies surveyed no longer want to be technically dependent on US cloud providers — yet 78% acknowledge they currently are. (Amaranth Advisory, 2025) Gartner has formalised the response strategy, naming geopatriation — the deliberate migration of workloads from global hyperscalers to local or sovereign providers — as a top strategic technology trend for 2026. By 2030, over 75% of European and Middle Eastern enterprises are expected to have geopatriated at least some workloads. (AI & Data Insider, 2025) The direction of travel is unmistakable.
The Support Gap Nobody Is Filling
Microsoft’s pivot is accelerating in another direction too. The simultaneous retirement of Windows 10, Office 2016/2019, and Skype for Business signals Microsoft’s accelerating pivot toward cloud-based, subscription services. The company is not in the business of supporting legacy environments. Its Extended Security Update programmes exist but are expensive — enterprise ESU costs for Windows platforms double each year — and they are explicitly temporary. (PCWorld, 2026)
This creates a structural support gap. Third-party support can cover workloads that Microsoft Unified Support no longer touches at roughly half the cost. (US Cloud, 2025) That is a credible and scalable business model — and it does not require being a global IT giant to execute. A regional ISP that understands its local customer base, speaks the same language, and can dispatch a technician or provide a support call in a familiar time zone is not a lesser alternative to a hyperscaler. For a small business owner trying to keep a Windows 10 machine running safely while they plan a hardware refresh, it is a better one.
The Opportunity in Plain Sight
Microsoft has simultaneously opened a reseller channel that regional ISPs are well-placed to exploit. Since December 2025, Microsoft 365 Copilot Business has been available through the Cloud Solution Provider programme for businesses with up to 300 users, priced at $21 per user per month with promotional rates running through June 2026. Microsoft’s own data suggests that for every dollar of Microsoft revenue, services partners earn $8.45 — a ratio that only increases with AI. (Pax8, 2025) A global price increase for Microsoft 365 is also coming in July 2026, creating an immediate window for partners to lock customers into current pricing and build long-term relationships in the process. (Microsoft Partner Centre, 2025)
Regional ISPs already have the billing infrastructure, the customer trust, and the local presence that large SaaS vendors lack. What they need is the product portfolio and the service wrap to match. Bundling Microsoft 365 licensing with a managed migration service — helping SMB customers move from Windows 10 to Windows 11, from on-premises Exchange to cloud mail, from legacy Office to subscription Microsoft 365 — is a natural extension of what ISPs already do. Adding a lifetime premium support tier on top of that, covering software troubleshooting, security patch management, and helpdesk access, turns a one-time migration into a recurring, defensible revenue stream.
The Window Is Open — For Now
The conditions creating this opportunity will not last indefinitely. The EOL migration wave will peak and subside. The sovereign cloud market will mature, and larger players will consolidate it. The Copilot promotional pricing will expire. But right now, in 2025 and 2026, there is a rare alignment of circumstances: mass customer vulnerability, hyperscaler retrenchment from legacy support, growing appetite for local alternatives, and a Microsoft partner programme actively recruiting regional resellers.
Regional ISPs that move decisively — building a software resale capability, wrapping it in genuine human support, and positioning themselves as the trusted local alternative to faceless hyperscalers — will emerge from this period with a fundamentally stronger and more diversified business. Those that wait for the dust to settle may find the opportunity has already moved on without them.
