Scheduled Networking Maintenance

On Tuesday 26th January, 2016, from 01:00- 06:00 CST, Rackspace
plans to perform a disruptive maintenance on several Cisco 6500 aggregation
routers in our DFW Data Center as part of a maintenance to proactively
replace line card modules affected by faulty memory DIMM.  During this
time, we expect there to be two losses of connectivity of around 30 seconds each
between Business Class Servers and this dedicated network device.

Also, there exists a possibility of a longer impact should any unforeseen
issues arise due to the hardware issue.  As such, we may expect up to
one hour downtime per router in the worst case.

Reminder: Scheduled Web Server Maintenance Today

Reminder that web server maintenance tonight, Monday Night, between 9pm and 11:59pm ET USA, will affect some customers:

  • Upgrade for PHP v5.2 to v5.5 for users of one shared web server
  • Migration to a new server and upgrade for PHP v5.4 to PHP v5.5 for users of another shared web server

Scheduled Firewall Maintenance

LuxSci is performing maintenance on its redundant hardware firewalls Sunday morning, November 22nd, between 12:01 am ET  and 1:00am ET.

During this time, LuxSci will be shifting Internet traffic from its two old redundant hardware firewalls to two new redundant hardware firewalls. This will affect all services — WebMail, email, SecureForm, web site hosting, etc. for almost all customers.

We expect several seconds to a minute of degraded or interrupted Internet traffic during the switch over.  The worst case and very unlikely scenario is up to an hour of downtime.

After the migration is complete, LuxSci will have new, redundant hardware firewalls more than twice the bandwidth throughput, much larger limits on maximum number of concurrent connections, VPN connections, and, of course, faster processors for traffic analysis and management.  This upgrade will be a benefit to all customers, both old and new.

Scheduled Web Server Maintenance: December 14th

LuxSci will be performing maintenance on two shared web hosting servers on December 14th, 2015.

This maintenance window is scheduled to last from 9pm to 11:59pm ET.

Maintenance operation #1

The shared web server used by many of our oldest clients is still running PHP v5.2 due to compatibility reasons with use of MySQL v4.0 by some customers.  At this point, we need to force everyone to upgrade to a recent version of PHP and MySQL both for compatibility with new versions of software and for security reasons.

This server is the one used by customers that use ftp.luxsci.com, ftp-5.luxsci.com, ftp-8.luxsci.com to access their sites (or anyone whose web site is using PHP 5.2).  If you are unsure, please ask support.

During the maintenance window, this server will be upgraded from PHP v5.2.x to PHP v5.5.x.  There is expected to be only a minute or so of downtime as apache is switched over.

However, any old customers using PHP to access very old MySQL v4.0.x databases on that server will lose access to those databases at that time, as newer versions of PHP cannot talk to MySQL v4.0.x.  As such, we are recommending that all such customers upgrade to MySQL v5.5 before this maintenance window.

How do you upgrade? This requires exporting your database, modifying the export slightly so it is compatible with MySQL v5.5.x, and then importing it into a new MySQL v5.5.x database.  Finally, you would update your web site to use the new database and then delete the old database.

If you want to upgrade “right now”, you can contact support and we will manually give you the modified export of your database.  Within the next week or so, our “Database Export” tool available in our web portal will be updated to automatically export  the “modified” databases for you so you can export and re-import your database yourself.

We recommend that all affected customers make this upgrade before the maintenance window.

Maintenance Operation #2

The second maintenance operation of this night will be the migration of all customers using an aging shared web server at Peer1 hosting into a new Business Class Virtual Server at RackSpace behind our firewalls and next to the rest of our new servers.  This change will bring a newer operating system, more horse power, more security and an upgrade from PHP v5.4 to PHP v5.5 to customers using this server.

The customers affected are those who use ftp-15.luxsci.com for access to their files.  If you are unsure, please ask LuxSci support.

During the maintenance window, there will be a period of 15-30 minutes of downtime as the server is moved and LuxSci updates the DNS settings for all affected web site domains for which we manage DNS.  For customers on this server who manage their own DNS and have setup DNS A records, they will need to update their DNS on or after the migration window to keep their sites online.

LuxSci will be announcing the new IP address of this server in the coming weeks and contacting customers who are managing their own DNS so that they can have a heads up on the needed coordination.

Scheduled Premium Email Filtering and Archival Updates


To improve the functionality of our Premium Email Filtering services, McAfee will be completing maintenance on Saturday, December 5th between 2:00 p.m. and 6:00 p.m. Mountain Standard Time (MST) which will result in periods of service impact for Premium Email Filtering and Email Archiving.

Timeframes: 
Begin: Saturday, December 5, 2015, 2:00 p.m. Mountain Standard Time (MST) (9:00 p.m. Greenwich Mean Time (GMT))
End:    Saturday, December 5, 2015, 6:00 p.m. MST (Sunday, December 6 1:00 a.m. GMT)

Impact:
During this four-hour maintenance window, the following services may be impacted:

  • Premium Email Filtering
  • Message Audit
  • Spam Quarantine
  • ClickProtect
  • Message Continuity
  • Email Archiving
  • Control Console

This maintenance may be completed prior to the end times stated above, however, McAfee is reserving the entire window to ensure adequate support for these enhancements. 

Reminder: Scheduled Web Server PHP Uprades

LuxSci will be updating a number of our shared web hosting servers next week, changing the version of PHP installed to v5.5.x from older, legacy versions.

Customers are advised to be sure that their web sites are compatible this version of PHP and that if they use IonCube or Zend loaders, that their sites will run once updated loader software is installed.  This change is being made for compatibility and security reasons.

Sometime during the maintenance window, we expect web hosting services to be unavailable for about 1-2 minutes as we effect this upgrade.  However, we are prudently reserving the entire window to resolve any issues that may arise.

The following maintenance windows and which servers they affect are scheduled:

Wednesday, November 18th, 9:00pm to 11:59pm Eastern time — web6.luxsci.com / ftp-6.luxsci.com and web3.luxsci.com / ftp-3.luxsci.com.
