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.
