The verdict in three sentences
For a mid-market enterprise, managed hosting turns passive hosting into contractually guaranteed availability: CAD 600-2,200/month for 99.9 to 99.99 % uptime, 24/7 monitoring and a recovery time < 1 hour. The real trade-off is not the retainer price but the cost of one hour of downtime on your site, which for an enterprise often runs into thousands of dollars. A good contract includes a tested DR plan, redundant backups, a CDN and enforceable penalties if the SLA is missed.
Managed hosting tiers and their SLA
2026 order of magnitude for managed hosting of an enterprise corporate site/portal in Toronto:
| Tier | Price/month | Guaranteed uptime | Recovery (RTO) | Monitoring |
|---|---|---|---|---|
| Standard | CAD 600-900 | 99.9 % | < 4 h | Business hours |
| Business | CAD 1,000-1,500 | 99.95 % | < 2 h | 24/7 |
| Critical | CAD 1,800-2,200 | 99.99 % | < 1 h | 24/7 + on-call |
The gap between 99.9 % and 99.99 % looks tiny but means 8.8 h vs 53 min of downtime/year. For a site generating revenue continuously, that gap alone justifies moving up a tier.
What the SLA really guarantees
A serious managed-hosting SLA is more than a percentage. Comparison of commitments:
| Commitment | Standard | Business | Critical |
|---|---|---|---|
| DR plan | Documented | Tested annually | Tested semi-annually |
| Redundant backups | Daily | 2 sites | 3-2-1 + geo-redundant |
| CDN included | Option | Yes | Yes multi-POP |
| Penalties if SLA missed | No | Partial credit | Credit up to 30 % |
| Acknowledgement time | 4 h | 1 h | 15 min |
| Monthly uptime report | Yes | Yes | Yes + quarterly review |
Demand that penalties be quantified and automatic: an SLA with no real penalty is just marketing.
Mini case study
Sarah, CIO of a 250-employee industrial enterprise in Toronto, runs a client/partner portal where quotes and orders flow. One hour of downtime blocks roughly CAD 6,000 of transactions and triggers support calls.
She moves from Standard (CAD 800/month) to Critical (CAD 2,000/month), i.e. +CAD 14,400/year. In return, uptime goes from 99.9 % (8.8 h/year) to 99.99 % (0.9 h/year): 7.9 h of downtime avoided, i.e. about CAD 47,000 of transactions preserved/year, not counting reputation. Net ROI: roughly 3x the extra cost, before even counting penalties in case of failure.

FAQ
How much does one hour of downtime cost an enterprise?
It depends on the revenue flowing through the site: for an active B2B portal, expect CAD 1,500 to 7,000/hour of blocked transactions, plus reputation and support impact. That figure should size your SLA.
What is the concrete difference between 99.9 % and 99.99 %?
99.9 % allows 8.8 h downtime/year, 99.99 % only 53 min/year. The higher tier is only justified if each hour of outage is costly.
What is a DR plan and why test it?
A DR (disaster recovery) plan defines how to restore service after a major incident. An untested DR plan is fiction: demand a documented test at least annually.
Are SLA penalties really paid?
Only if they are quantified and automatic in the contract (10-30 % credit of the monthly retainer). Without a precise clause, the penalty stays theoretical.
Is a CDN essential in managed hosting?
For a nationally/internationally trafficked site, yes: the CDN cuts latency and absorbs spikes. It is included at Business and Critical tiers, optional at Standard.
