Lumen vs Frontier Business
Both Lumen and Frontier sell DIA fiber to businesses, but they target different markets. Lumen has stronger national coverage and 99.99% SLA. Frontier is often $50-100/mo cheaper in markets where they overbuilt, with a slightly looser 99.9% SLA. Footprint usually decides.

When to choose Lumen
You need the tighter 99.99% SLA, faster repair commitment, multiple static IPs out of the box, or you're outside Frontier's footprint.
When to choose Frontier Business
Frontier overbuilt fiber in your area and is offering aggressive pricing. The SLA difference (99.99% vs 99.9%) translates to about 50 minutes more downtime per year — acceptable for most non-mission-critical use cases.
The honest bottom line
Frontier wins on raw price in markets where they have fiber. Lumen wins on SLA and IP allocation. For a 30-person office where saving $50/mo matters more than 50 extra minutes of theoretical downtime, Frontier is fine. For a healthcare or finance operation, Lumen's tighter SLA is worth the premium.
