Why Your PMS uptime record matters more than you think

What is uptime — and why does the percentage matter?

Uptime is the percentage of time your software is working as it should. Downtime is everything else: the outages, the errors, the "we're experiencing issues" messages that arrive at the worst possible moment.

It sounds like an IT concern, but for a holiday letting agency, it's a business-critical one. Your PMS is the engine behind your bookings, your guest messaging, your owner statements, and your channel listings. When it stops, everything stops.

What does downtime actually cost you?

Here's what happens to your business when your PMS goes offline — even briefly:

• No bookings come in. If a prospective guest hits an error page, they book elsewhere. That booking is gone.
• Automated guest messages don't send. Confirmations, check-in instructions, reminders — all paused.
• Google notices. Search engines can lower your ranking if your site is frequently unavailable, undoing months of SEO work.
• Pay-per-click spend is wasted. Ads keep running; clicks go nowhere.
• Double bookings become a real risk. If you use a channel manager, an outage can break the sync that prevents the same property being booked twice.
• Owner trust erodes. Property owners expect their listings to be live and bookable. Downtime is hard to explain.

A single significant outage can affect all of the above simultaneously.

The 98% myth

Many software providers advertise a 99% or even 98% uptime guarantee and present it as reassuring. Run the numbers and it looks different.

A service running at 98% uptime is offline for roughly 14 hours per month. Over a year, that's 168 hours — more than seven full days — when your business is invisible and unbookable. Summer weekends included.

The headline percentage sounds minor. The hours add up fast.

What we do differently at Bookster

We don't just aim for high uptime — we publish it. Our public status page tracks our record in real time, so you don't have to take our word for it.

Behind the scenes, here's how we maintain that record:

• Redundant infrastructure. If one component fails, we can migrate to a backup node quickly — without waiting for a manual fix.
• Careful deployments. Every update goes through regression testing before it reaches the live platform. We can roll back any change if something unexpected surfaces.
• Active monitoring. We watch system health continuously, not reactively.
• Hosting partners we trust. We work with Linode, a provider with a strong industry reputation, and we review that relationship regularly.

We do occasionally plan short maintenance windows for upgrades. When that happens, we give clients advance notice — it's never a surprise.

What to look for when evaluating a PMS on reliability

If you're currently weighing up your options — or reconsidering your current provider — here are the questions worth asking:

1. Do they publish a public status page with a real uptime history?
2. How do they communicate during an outage — and how quickly?
3. What's their actual SLA (service level agreement), and what happens if they breach it?
4. Do they have redundant infrastructure, or does one server failure take down the whole platform?
5. Can you find independent reports of recent outages from other customers?

A provider that's confident in their uptime record will answer all of these without hesitation.

Frequently Asked Questions

What is PMS uptime and why does it matter for holiday rentals?

Uptime is the percentage of time your property management software is fully operational. For holiday rental businesses, downtime means lost bookings, failed guest communications and potential double bookings — all of which have a direct financial cost.

How much downtime does a 98% uptime guarantee actually mean?

A 98% uptime record translates to roughly 14 hours of downtime per month, or around 168 hours per year. That's over seven full days when your business isn't available to take bookings.

Does Bookster publish its uptime record?

Yes. Bookster maintains a public status page at status.booksterhq.com where you can view the real-time and historical uptime record.

What happens to my bookings if my PMS goes offline?

During an outage, you will typically receive no new bookings, automated guest messages won't send, and — if you use a channel manager — there is an increased risk of double bookings. Pay-per-click ad spend is also wasted if clicks lead to an unavailable site.

What should I look for in a reliable PMS provider?

Look for a public status page with real uptime history, clear communication during outages and a consistent track record you can verify independently.
