Infrastructure and Reliability
What degree of reliability do you need?
Home > About LuxSci > Reliability > Infrastructure
Our high availability infrastructure is designed and configured with many layers of redundancy and a highly customized architecture to prevent any interruption to your ability to access your email from anywhere at any time.
| Feature | |
|---|---|
Security Certifications: SSAE16, ISO27001, SOC 1, SOC 2, SOC 3, Safe Harbor, CPS |  |
High Speed Internet Access | |
Redundant backbone connections to redundant Gigabit and multi-Gigabit
networking hardware all the way to each server
provides fast, reliable connectivity. | |
Conditioned, Redundant Power | |
Redundant N+1 UPS power supplies and an on-site diesel
generator that can run indefinitely. Individual servers
also use redundant, hot swappable power supplies. | |
RedHat and CentOS Linux | |
OpenSource Software | |
We use: Apache, MySQL, sendmail, Panda IMAP
(mix folders), Procmail, and PGP. WebMail and other specialized software
running on top of the infrastructure are proprietary, developed by LuxSci. | |
Redundant Disk Subsystems | |
We use redundant disk subsystems (Hot Swappable SSD RAID 10 and SAS RAID 5) to
protect your data against the possibility of disk failure. In the case of
disk hardware failure, your servers will keep running as usual and we can
replace the affected disks with zero downtime and zero data loss. | |
Intrusion Detection Systems | |
Multi-Stage Email Delivery | |
LuxSci uses multiple levels of email servers to protect you from
mass-emailing viruses and worms and to off-load the effort of spam, virus,
and custom email filtering. Unlike many hosts, the email server used for
email access and sending is NOT the same as those used for inbound email
processing! | |

High Availability
Our shared Enterprise Class Hosting and our Premium Dedicated servers run on a high availability (HA) dedicated private cloud server infrastructure.
| Feature | |
|---|---|
High Availability Redundant Hardware Firewalls | |
Multiple high capacity hardware firewalls configured redundantly so
that if any one should fail, the others will automatically take over. | |
High Availability Redundant Hardware Load Balancers | |
Multiple high capacity hardware load balancers configured redundantly so
that if any one should fail, the others will automatically take over. | |
High Availability Redundant Network Switching | |
All network switching is setup using redundant, bonded network
interfaces and switches, so that if a network card or cable or switch
fails, the network traffic flow to and from the servers will not be
affected. | |
High Availability Central Data Storage | |
All server data is stored in a centralized storage array that includes:
This gives large amounts of high capacity, fast disk space. It enables quick recovery from any disk failure and minimizes that chance of multi-disk failure. It also provides high availability through redundant data pathways and processors through the system to the servers. | |
High Availability Servers | |
Premium Dedicated Servers and Premium Shared Servers (as well as other
components of our system) are run on VMWare virtual machines running
vMotion. This allows the virtual servers to recover instantly from
hardware failure on the underlying hypervisor servers. Failure of
RAM, CPU, or other inherently non-redundant server components could crash
an underlying hypervisor .... but the servers will be quickly and
automatically moved to other hypervisors while the problem one is repaired.
This minimizes and mitigates any downtime due to hardware failure. | |
Redundant Inbound Email Infrastructure
At LuxSci, redundancy is the key to successful email delivery. Our inbound email servers, which are separate from your email storage servers, are set up in a redundant failover configuration so that your mail is always delivered quickly and correctly even if a server fails or becomes unavailable for any reason. In the unlikely event that your email storage server becomes temporarily unavailable, backup spools will automatically queue your mail and retry delivery to ensure that no mail gets dropped or lost and that it gets delivered as fast as possible.
LuxSci uses multiple levels of email servers to protect you from the impact of email floods due to mass-emailing viruses and worms and to off-load the effort of spam, virus, and custom email filtering.
Server Health Monitoring
LuxSci employs extensive server monitoring to ensure the health and reliability of all shared and dedicated servers. This includes:
- Constant remote monitoring of all service ports on all servers to detect service or connectivity issues.
- A custom server health monitoring suite runs on every machine and constantly scans for a vast array of different kinds of problems -- configuration, abuse, etc. -- and either mitigates the problems itself or alerts support so that steps can be taken to ensure that the problem has minimal or no impact on our users.
Email Block List Avoidance
While any email server at any provider can be block listed easily and without notice, LuxSci's acceptable use policy and monitoring make the block listing of LuxSci's email servers a rare event. In the event that a server does get block listed, LuxSci has the ability to quickly (within minutes of identifying the issue) re-route email from the affected server around the blocks so that email can be delivered while LuxSci works with the company managing the block list to remove our servers.*
*Applies to customers using our premium (non-bulk) SMTP services, not to our High Volume Outbound Emailing service.
