Infrastructure
Our infrastructure is designed and configured with many layers of
redundancy and a highly custom architecture to prevent any interruption
to your ability to access your email from anywhere at any time.
- High Speed Internet: A multi-homed network
with DS3 to OC12 connections through AT&T,
Qwest, Sprint, Time Warner, UUNET, and WilTel
provides fast, reliable connectivity.
- Conditioned Power:
Redundant N+1 UPS power supplies and an on-site diesel
generator that can run indefinitely.
- Technology:
We use: RedHat Enterprise Linux, Apache, MySQL, sendmail, Panda IMAP
(mix folders), Procmail, and PGP. WebMail and Infrastructure software are
developed by LuxSci.
- Redundant Disk Subsystems:
We use redundant disk subsystems (Hot Swappable SCSI 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.
- 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.
- All of our shared servers use SCSI RAID-5 disk subsystems and
redundant power supplies to protect your critical data against potential
hardware issues.
Service Level Agreements (SLAs)
Our Service Level Agreement is our commitment to reliability put in
writing.
LuxSci guarantees as 99.99% or better system uptime for all shared
hosting accounts. The SLA for dedicated servers is even better.
Data Backups & Restores
To insure the integrity of your web and email data, we perform nightly
backups of all your data to machines in the same data center as your
servers. Furthermore, we perform archived weekly backups of all your data
to machines located in a geographically distant off-site location. These
archives are kept for one month.
Your account can have data restored from backup once per month at
no additional cost. Unused restores accumulate from month to month
as credits towards your future restore needs. If you require data to be
restored from backup more times that you have restore credits, there will
be a fee of $25.00 per additional restore (or more depending on the
complexity or amount of recovery necessary).
If you require a customized backup schedule, or that archives of your
data be kept for a longer period of time, contact sales for a custom quotation.
Customization of the backup and restore policies are available to accounts
with dedicated servers.
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 Blacklist Avoidance
While any email server at any provider can be blacklisted easily and
without notice, LuxSci's acceptable use policy and monitoring make the
blacklisting of LuxSci's email servers a rare event. In the event that a
server does get blacklisted, 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 black list to remove our servers.

Listen to Our Clients: "I email to commend LuxSci's excellent email and web services, which in my opinion, are similar to a well-built German motor vehicle. Very reliable technology with constant innovations (but no gimmicks) and slick WebMail. Moreover, never before have I experienced such swift customer service. Most emails are replied to within minutes at all times of day. Keep up the good work!" Rick Wild
