# Service Level Agreement (SLA)
|
||
|
||
**Arcline IT LLC**
|
||
Last updated: May 2026
|
||
Applies to: All Arcline shared hosting, WordPress hosting, and VPS hosting services.
|
||
|
||
---
|
||
|
||
## 1. Overview
|
||
|
||
This Service Level Agreement ("SLA") governs the availability and performance
|
||
of services provided by Arcline IT LLC ("Arcline", "we", "us") to you ("Customer").
|
||
This SLA is incorporated by reference into the Arcline Terms of Service and
|
||
Master Service Agreement.
|
||
|
||
Arcline operates self-hosted infrastructure on owned hardware. We do not use
|
||
AWS, Azure, GCP, Cloudflare, or any hyperscale cloud provider. We are
|
||
transparent about what this means for availability, and we believe honesty
|
||
about our capabilities serves our customers better than inflated promises.
|
||
|
||

|
||
|
||
## 2. Uptime Commitment
|
||
|
||
| Service Tier | Monthly Uptime Target | Annual Uptime Target |
|
||
|-------------|----------------------|---------------------|
|
||
| Shared Hosting | 99.0% | 98.5% |
|
||
| WordPress Hosting | 99.0% | 98.5% |
|
||
| VPS Hosting | 99.5% | 99.0% |
|
||
| Network (edge) | 99.5% | 99.0% |
|
||
|
||
**Calculated as:**
|
||
```
|
||
Uptime % = (Total Minutes in Month − Downtime Minutes) ÷ Total Minutes × 100
|
||
```
|
||
|
||
---
|
||
|
||
## 3. Service Credits
|
||
|
||
If we fail to meet the uptime target in a given calendar month, you may request
|
||
a service credit. Credits are applied to your next invoice and are not
|
||
redeemable for cash.
|
||
|
||
| Monthly Uptime | Credit |
|
||
|----------------|--------|
|
||
| Below target but ≥ 95% | 10% of monthly fee |
|
||
| 90% – 94.99% | 25% of monthly fee |
|
||
| Below 90% | 50% of monthly fee |
|
||
|
||
### How to Request a Credit
|
||
|
||
1. Email **support@arcline.it** with subject line "SLA Credit Request"
|
||
2. Include your account email and the month in question
|
||
3. We will verify our monitoring data and respond within 5 business days
|
||
|
||
Credits must be requested within 30 days of the end of the month in which
|
||
the downtime occurred.
|
||
|
||
**Limitation:** Total credits in any single month shall not exceed the
|
||
Customer's monthly service fee for the affected service.

||

|
||
## 5. Monitoring
|
||
|
||
Arcline measures uptime using our internal monitoring system (`arcline-uptime`),
|
||
which performs checks from multiple locations at 1-minute intervals. Monitoring
|
||
results are available at [status.arclineit.com](https://status.arclineit.com).
|
||
|
||
We monitor:
|
||
- **HTTP services** — connection success, HTTP 200 status, response within 10s
|
||
- **TCP services** — successful TCP connection to service port
|
||
- **Network** — ping response from edge router
|
||
- **Infrastructure** — system load, disk usage, temperature sensors
|
||
|
||
In the event of a disagreement about uptime, Arcline's monitoring data shall
|
||
be the primary source. Customers are encouraged to run independent monitoring
|
||
and may submit their own monitoring data for consideration.
