Frequently Asked Questions (FAQ)
Here’s a list of frequently asked questions that we’ve received in the past, along with a short answer. If you have a question, feel free to ask us!
1. What is a low uptime?
Uptime tells us the percent of the time while your website or service is up. This means that an uptime of 90% would be 9 out of 10 days of working website, and one day that’s not. What would the clients of a business think when they see that every 10 days the website doesn’t work.
These are the allowed downtimes for specific uptime percentages:
|Availability %||Downtime per year||Downtime per month||Downtime per week|
|90% (“one nine”)||36.5 days||72 hours||16.8 hours|
|95%||18.25 days||36 hours||8.4 hours|
|99% (“two nines”)||3.65 days||7.2 hours||1.68 hours|
|99.9% (“three nines”)||8.76 hours||43.2 minutes||10.1 minutes|
|99.99% (“four nines”)||52.56 minutes||4.32 minutes||1.01 minutes|
We consider a low uptime anything below 98%, which means about 3 hours per week.

2. What is a slow site?
A good response time is usually under 0.8 seconds, or 800 milliseconds. Between 0.8 seconds and 1.2 seconds, the page loads rather slow, but still safe for the user’s experience. Over 1.2 seconds, the page is considered to load slow, and you have many downsides for this:
- poor usability will cause visitors to leave your site;
- Google Bot measures loading time and will downgrade your website in search results;
- a spike in the website’s traffic could render the website unusable (timeouts and very large loading times);
So if your site suffers from slow loading times, you should find out what the problem is a fix it.
