Premium WordPress Hosting Service - SLA
Service Level Agreement
ETRN believes in giving our customers the best service possible. So we provide your business with a 99.99% uptime service level agreement for our Premium WordPress Hosting services.
A 99.99% uptime SLA means that you should expect less than 53 minutes of unscheduled downtime over the course of a year. We take this further and seek to reach more than 99.999% availability.
Many of our competitors only offer a 99.9% or 99.95% uptime guarantee. And while that difference may not seem significant, the difference actually amounts to a downtime of 4 to 8 hours.
| Availability % | Downtime per year |
|---|---|
| 99.8% | 17.52 hours |
| 99.9% (“three nines”) | 8.76 hours |
| 99.95% | 4.38 hours |
| 99.99% (“four nines”) | 52.56 minutes |
| 99.999% (“five nines”) | 5.26 minutes |

Here is the text of our SLA:
-
SERVICE AVAILABILITY ETRN will make the Services available 99.99% of the time, excluding any Excused Downtime. In a given calendar month, we calculate “Service Availability” as follows:Service Availability = (total minutes Services are available × 100) / (total minutes in the month − Excused Downtime)
-
EXCUSED DOWNTIME“Excused Downtime” means the length of time the Services are unavailable due to:
- Scheduled Maintenance; includes any maintenance performed during established maintenance windows for which we provide reasonable notice or coordination with you in advance of the maintenance.
- Emergency Maintenance; means any maintenance performed outside the Scheduled Maintenance windows without advance notice where such maintenance is reasonably and urgently required to protect the integrity, availability, or security of any online systems.
- Beta Services;
- Force Majeure events; and
- The actions or omissions of you, your Authorized Users, or any third-party acting on your behalf or at your direction, including any unauthorized use of the Services, breach of the Agreement or Acceptable Use Policy, or any use or configuration of the Services that exceeds ETRN’s recommendations or advertised limits.
-
SLA CREDITSYou are entitled to a credit of 5% of the applicable monthly Fees for each half hour of downtime in excess of the Service Availability targets. (For example, you will receive a 5% credit for between 1 and 30 minutes of downtime in excess of the Service Availability targets, a 10% credit for between 31 and 60 minutes, etc.) In order to receive a credit, you must contact Support within 30 days of the event giving rise to the credit. Credits are based on our monitoring, shall not exceed 100% of the applicable monthly Fees, may not be carried over or aggregated, are forfeited at the expiration or termination of the Agreement, and will not be paid or provided as a refund.
We Answer Your Questions: FAQ
Q: What is the maximum e-mail attachment size?
A: The ETRN.com e-mail servers do not limit the size of individual e-mail attachments. The ETRN.com e-mail servers do impose a 400 MB maximum total message size limit. Individual customers can choose a smaller message size limit. We can also customize the handling of "oversized" e-mails. Please contact us to discuss your specific needs. A couple of important facts:
1. Attachments are typically encoded in what is called Base64[1]. As a result, the actual length of MIME-compliant Base64-encoded binary data is usually about 137% of the original file size.
2. E-mails often contain both plain text and HTML components. This also increases the overall size of the e-mail.
