Is tier 1 or 3 better? In layman’s terms, tier 1 companies are the big guns, and the tier 3 ones are the more modest firms. Over time, companies can move up the tiers if they fit the criteria.

What is a Tier 4? You must stay at home and only travel for work, education or other legally permitted reasons. If you must travel, you should stay local, and reduce the number of journeys you make. You must not leave a Tier 4 area or stay overnight away from home.
What is the difference between Tier 3 and Tier 4? Tier IV data centers have an availability of 99.995% and 0.8 hours of interruption per year compared to 1.6 hours of interruption with a Tier III facility. That is half of the downtime represented by a Tier III data center.
