Uptime is one of the crucial parameters used to measure the performance of a web hosting platform. In simplest terms, this is the time during which your web host remains up and running or more specifically does not have any downtime.
A lot of times you would come across web hosts providing a specific uptime guarantee like 99.9% or 99.99%. This would help you judge the worst case downtime that your web host might suffer.
Uptime also referred to as web host’s availability is usually provided for a period of 30 days.

Few web hosting companies offer a Service Level Agreement. An SLA would carry the exact terms about the guaranteed level of uptime.
In most cases, if the web host fails to maintain the required level of uptime, then the web host is liable to provide a refund or hosting credits.
This is an important piece of the agreement since this defines what you would receive as a compensation in case of an exceeding downtime.
The SLA terms and conditions differ from one web host to another and hence it is important to go through all the terms before choosing any hosting platform.
Uptime guarantee is definitely important for both the web host as well as the customer. A web host defines the uptime guarantee in multiples of 9 and is defined as a percentage.
A common uptime guarantee provided would be 99.99%, 99.9% or 99%. This is defined for a period of 30 days.
Each uptime metrics defines a specific worst case downtime as well. For instance, a 99% uptime would also mean a worst case downtime of 7 hours and 12 mins.
Similarly, a 99.9% uptime would imply a downtime of 43 mins and 12 sec. This is something that most web hosts offer.
While a 99.99% uptime implies a downtime of 4 mins and 19 sec. Most web hosts do not provide a guarantee above this value.
While it sounds appealing to choose a web host which guarantees a high uptime, one also needs to consider the pricing. In certain cases, a higher uptime guarantee would mean a higher cost.
This is a common trade-off between uptime and costs and one needs to choose an intermediate solution. It’s practically impossible for a web host to guarantee 100% uptime.
Few web hosts provide good uptime and in most cases provide 100% uptime, but not guarantee a consistent 100% uptime. Based on your business requirement and budget you need to choose the web host.
A web host’s uptime guarantee does provide a sense of relief. However, at the same time, one needs to ensure this does not overshoot your budget.
You can pick a good web host which provides substantial uptime along with other useful features such as backups, cache management, and quick restoration.
A web host provides a 99.9% uptime guarantee on the SLA. This also states the site has to be down for at least half an hour continuously to get an automatic credit. Also stated in the fine print is that you can send a documented downtime recorded at your end. In case this matches with their logs then you get the credit
Uptime guarantees are always overwhelming and eye-catching. However, there are few things which you should consider-
An uptime guarantee puts you in a safer zone. A web host which needs to pay for an unprecedented downtime is going to be more serious to ensure they maintain the required uptime.
When a web host provides compensation for all its hosted websites, then definitely it is going to ensure your website remains up and running as per the uptime guarantee. Needless to mention, failing to abide by the required uptime can burn holes to their pockets in the long run.
Ensure you choose a web host which can provide an uptime guarantee wherein the worst case downtime is affordable and is within the expected limits.
