Most 'unreliable IT' is really undocumented IT. Here is the audit-first approach we use to stabilise a multi-site estate in under six weeks.
When a business tells us its IT is unreliable, the root cause is rarely the hardware. It is almost always a lack of documentation: nobody knows how the network was built, what changed last, or which device does what.
We start every engagement with a physical and logical audit — every switch, access point, firewall rule, licence and backup job recorded in one place. Only then do we design the target estate.
For a four-office professional services client, that audit revealed three consumer-grade routers doing business-critical work and a backup that had not completed successfully in eleven months. Replacing the network was the easy part; proving recovery was the valuable part.
Six weeks after handover, connectivity tickets were down 97% and the client owned a documentation pack that any competent engineer could pick up. That is the standard we hold every technology engagement to.
