Umbraco hosting is the centre of everything. Every version from v4 to v17+. Modern containerised infrastructure on GreenStack, legacy Windows hosting for older installs, dedicated infrastructure for sites that need it.Around that we run the services Umbraco customers ask us for: domain registration, DNS, business email through Microsoft 365, Google Workspace or our own IMAP platform, Azure managed services for teams already on Azure, and CI/CD pipeline implementation. We also run a small WordPress hosting service for customers who have a WordPress site alongside their Umbraco one, same support team, same commitment to doing it properly.What we're not is a generalist. Sixteen years of working primarily with one platform is the reason our support team solves problems in twenty minutes that other hosts escalate for two days. We don't run discount shared hosting, we don't farm out support to first-line ticket triage, and we don't pretend to be experts in things we aren't.If you're running Umbraco - at any version, at any scale, anywhere in the world - we're built for you. If you're running something alongside it, we can probably help with that too. ... Read more
