In manufacturing, Every Minute of IT Downtime Costs You Twice

First you lose production. Then you pay again in overtime, rework, late penalties, and frustrated customers.

For many plants, the root cause isn’t the machines on the floor—it’s the systems behind them: MES, ERP, and SCADA running on outdated, underpowered, or poorly maintained IT infrastructure.

At Impress Computers & IT Services, we see the same pattern again and again:

  • “The MES hangs every morning at shift change.”
  • “SCADA screens freeze when we push a big batch.”
  • “ERP is so slow near month‑end that planners just give up.”

This post lays out why this happens, what “good” looks like, and how to systematically fix it—without disrupting production.

Why MES, ERP, and SCADA Go Down So Often

Most recurring outages can be traced back to a few underlying issues:

  1. Aging, Underpowered Servers
  • Legacy Windows Server versions, no longer supported.
  • Servers that were sized for yesterday’s data volumes and user counts.
  • Single points of failure: one box running “everything.”

Symptoms:

  • Slow screen refreshes, timeouts, spinning cursors.
  • MES or SCADA services that “randomly” stop.
  • Systems grind to a halt during peak usage (morning, shift handover, month end).
  1. Poor Preventive Maintenance

Manufacturing understands preventive maintenance for equipment—but IT often gets the “run to failure” treatment:

  • No regular patching or performance tuning.
  • Logs filling disks.
  • Antivirus scans scheduled during peak production hours.
  • Backups not tested, or failing quietly.

Symptoms:

  • “Out of space” errors.
  • Frequent reboots as the only “fix.”
  • Lost data after a crash.
  1. Network Bottlenecks and Weak Industrial Connectivity

MES, ERP, and SCADA are only as reliable as the network between PLCs, HMIs, servers, and user terminals:

  • Old switches, unmanaged, with no monitoring.
  • Flat networks without segmentation between office IT and OT.
  • Poor Wi‑Fi in production areas, or unmanaged industrial access points.

Symptoms:

  • Intermittent connection losses to machines.
  • SCADA tags going stale or alarm floods.
  • ERP or MES “seems fine in the office, terrible on the floor.”
  1. No Clear Ownership Between IT and OT

Modern manufacturing systems sit between traditional IT and operational technology (OT):

  • Who owns the MES server—IT, engineering, or the vendor?
  • Are upgrades coordinated with production schedules?
  • Does anyone have a full, up-to-date map of dependencies?

Symptoms:

  • Finger-pointing between vendors, IT, and engineering.
  • Long MTTR (mean time to repair) for every outage.
  • Change management by email and sticky notes.

What “Good” Looks Like: A Stable, Resilient Manufacturing IT Stack

A well-designed environment for MES, ERP, and SCADA has a few non‑negotiables:

  1. Right-sized, modern server infrastructure
    Capacity for current loads plus planned growth, built with redundancy.
  2. High-availability where it matters most
    Failover capabilities so a single hardware failure doesn’t stop production.
  3. Structured patching and maintenance
    Planned windows aligned with shifts and production plans, not mid-batch.
  4. Monitored networks with clear segmentation
    IT and OT separated but integrated; issues detected before users feel them.
  5. Documented ownership and escalation paths
    Everyone knows who to call, and who is responsible for what.

That’s the standard we design and maintain for our manufacturing clients at Impress Computers & IT Services.

Practical Solutions to Cut Downtime and Stabilize Your Systems

Here’s how we typically help plants move from reactive firefighting to stable, predictable IT performance.

  1. Infrastructure Assessment Focused on MES/ERP/SCADA

We start with a targeted health check, not a generic audit:

  • Current server specs, OS versions, and virtualization setup.
  • Resource utilization (CPU, RAM, disk, I/O) over time.
  • Storage capacity, backup status, and recovery capability.
  • Network mapping between PLCs, HMIs, servers, and user endpoints.

Deliverable:
A clear report that says, in plain language:

  • “Here are your top 3 risks for downtime.”
  • “Here’s what each one could cost you in production hours.”
  • “Here’s the minimum we recommend to stabilize the environment.”
  1. Right-Sizing and Modernizing Your Server Environment

Instead of guessing at specs, we size based on real workloads, vendor requirements, and your planned growth:

  • Migration from aging physical servers to virtualized or hybrid setups.
  • Dedicated resources for critical systems (e.g., separate VMs for MES database vs. application).
  • Storage tuned for database-heavy workloads (IOPS, not just gigabytes).

With Impress, this includes:

  • Planning and execution of migrations with minimal or no production impact.
  • Coordination with your MES/ERP/SCADA vendors to ensure full support.
  • Rollback plans so your plant is never “stuck” mid-upgrade.
  1. High Availability and Redundancy Where It Counts

You don’t have to make everything highly available—but your bottlenecks and critical systems should be:

Options we commonly implement:

  • Clustering for key databases (e.g., MES/ERP DB).
  • Redundant application servers behind load balancers.
  • Dual power supplies and redundant network paths for core hardware.

Result:

  • A failed server or switch becomes a maintenance ticket, not a plant-wide emergency.
  1. Structured Patch Management and Change Control

We bring manufacturing discipline to IT maintenance:

  • Maintenance windows agreed in advance with operations.
  • Staged updates (test → pilot line → full rollout).
  • Backout plans for every change.
  • Clear communication so supervisors and operators know what to expect.

Impress can own the entire lifecycle:

  • Track patch levels and vendor compatibility.
  • Apply OS and firmware updates on a defined cadence.
  • Provide post-change checklists to confirm systems are healthy.
  1. Network Hardening and Visibility

We make your industrial network predictable and observable:

  • Segmentation of IT and OT with controlled, monitored bridges.
  • QoS (Quality of Service) to prioritize critical plant traffic.
  • Industrial Wi‑Fi designed for roaming devices and harsh environments.
  • Centralized monitoring to catch:
    • High latency
    • Packet loss
    • Flapping interfaces
    • Broadcast storms

Our team sets up dashboards and alerts so we can often fix an issue before your operations team notices it.

  1. Proactive Monitoring of MES, ERP, and SCADA

Beyond infrastructure, we monitor the applications themselves:

  • Service status (is MES/SCADA actually running and responsive?).
  • Transaction times and error rates.
  • Disk and log growth specific to your applications.

With Impress managed services:

  • We receive alerts when trends look dangerous (e.g., logs filling a drive, DB responding slowly).
  • We act before “slow” turns into “down.”
  • You get monthly summaries in plain English, not just charts.

  • Fix any “red alert” issues (disk space, failing backups, obvious bottlenecks).
  • Implement basic monitoring and alerting.

Weeks 3–6: Optimization & Risk Reduction

  • Right-size key servers and tune databases.
  • Adjust backup schedules and test restores.
  • Fix the worst network bottlenecks affecting MES/SCADA.

Weeks 7–12: Long-Term Reliability Plan

  • Present a roadmap: hardware refresh cycles, high availability options, network improvements.
  • Align IT maintenance with your production calendar.
  • Agree on SLAs and communication protocols for incidents and changes.

Result: Measurably less downtime, faster systems, and fewer surprises.

Ready to Turn Downtime into Predictable, Stable Operations?

If your team is tired of:

  • MES or SCADA “mysteriously” going down,
  • ERP slowing to a crawl at the worst possible moments, or
  • Vendors and internal teams pointing fingers while production waits,

then it’s time to put a manufacturing-focused IT foundation in place.

Impress Computers & IT Services helps manufacturers:

  • Stabilize MES, ERP, and SCADA.
  • Reduce unplanned downtime.
  • Gain clear visibility into IT risks before they hit the shop floor.

Contact us to schedule a no-obligation infrastructure health check tailored to your production systems.

Let’s make your IT as reliable as the best machine on your floor.

 

Q1: How do I know if my IT infrastructure is really the cause of our production issues?
A: Look for recurring patterns: MES hanging at the same time each day, SCADA freezing during large batches, or ERP slowing down at month end. If operators say “it always happens when…” that’s a strong indicator of infrastructure or network bottlenecks. During our infrastructure health check, we correlate these symptoms with actual data (CPU/RAM usage, disk I/O, network latency, error logs) to confirm whether IT is the root cause—and identify exactly where.

Q2: Can we improve uptime without shutting down production or doing a big “rip and replace”?
A: Yes. Most of the gains come from targeted, phased improvements—not wholesale replacement. We prioritize high-impact, low-disruption changes first: stabilizing backups, fixing storage and network bottlenecks, adjusting maintenance windows, and right-sizing key servers. Migrations and upgrades are planned around your production schedule, with rollback plans so you’re never stuck mid-change.

Q3: We already have an internal IT team. How would Impress work with them?
A: Many of our manufacturing clients use us in a co-managed model. Your internal team keeps ownership of day-to-day user support and internal priorities, while we handle plant-critical areas like MES/ERP/SCADA infrastructure, network design and monitoring, patch management, and vendor coordination. We establish clear roles, escalation paths, and SLAs so your IT staff are supported—not replaced—and production gets the reliability it needs.
