When it comes to uptime, it pays to read your hosting agreement very carefully. Most uptime guarantees refer to network uptime only...nothing else. ICO's network uptime guarantee is 99.999%...or 26 seconds downtime a month. But our 99.999% guarantee covers more than just network uptime; it covers electrical and air-conditioning as well. It's in writing in every ICO agreement.
Where there is sometimes confusion, particularly with dedicated servers, is in all the other things that go into making up a live site. Everything from server RAM to application error to corrupted data to failed firewall. Are they covered by an uptime guarantee or SLA?
Almost never. And rarely advertised publicly. Until now. ICO provides guarantees and SLAs on everything in the hosting chain, provided our advice is followed.
Below, we'd like to outline the hardware and software components of a typical redundant system (all ICO hosting solutions are completely custom-designed). This system has a large degree of redundancy built into it, and this allows us to make an overall guarantee as to its reliability, covering:
- The Operating system
- Your Application
- Database Availability
- Hardware Uptime
- Firewall Failover
- Network Availability
- Electrical Power
- Air-Conditioning
We are confident enough to provide a four-hour maximum window of downtime guarantee for the complete package.# Most individual parts of the system will be restored much faster (instantaneously).
Please remember that we are talking about everything above. Operating system, database availability, your application, hardware uptime, firewall failover, network availability, electrical power, air-conditioning; everything that is within our power to control. We can offer even higher uptime guarantees on other systems.#
