Scheduled Email Server Reboot

LuxSci will be rebooting one shared email server to add additional resources (CPU and RAM) to it.    We are reserving the maintenance window of 8pm to midnight on Wednesday, August 26th to perform this reboot.  This reboot is expected to interrupt services for only about 1-2 minutes; however, LuxSci technicians will be on stand by just in case.

Customers affected have shared enterprise class services on servers 10, 13, and 25 — e.g. pop-10.luxsci.com, secure-email-13.luxsci.com, secure-email-25.luxsci.com, etc.  If you are unsure, please contact LuxSci support.

 

Scheduled WebServer Maintenance: August 21st

LuxSci will be updating Apache, PHP, and openssl software on a few shared and dedicated and web servers this Friday.

This will occur in a rolling fashion during the following maintenance window:

  • Friday: 5pm-11pm ET

When your web server is updated, you may expected a few seconds of downtime as the apache server is stopped and then started again.

The shared web server to be updated is “web15.luxsci.com” or “ftp-15.luxsci.com”.  This is the shared server used by legacy business class customers.  Several dedicated servers will also be updated… support tickets will be made in these customer accounts.

In addition to updating PHP, the primary goal of this maintenance is to upgrade these web servers from Apache v2.2.x to v2.4.x.

Restricting direct Remote MySQL Access

In the coming 1-2 weeks, LuxSci will be restricting remote access to very old hosted MySQL instances for security reasons.  Customers connecting directly on port 3306 from locations outside of the LuxSci infrastructure will find their connections blocked.

Customers who require remote MySQL access are recommended to use our VPN service.   Please contact LuxSci support for more information.

In the coming months, direct remote access to all hosted MySQL instances on port 3306 will similarly be suspended with VPN and other secure remote access methods being recommended instead.

Note that MySQL access from LuxSci shared and dedicated web servers is not and will not be affected by these changes.  These restrictions only apply to remote access; e.g. access from your workstation or from servers provided by other companies.

Scheduled Business Class Server Maintenance: August 19th

Rackspace will be performing network maintenance that will impact all shared and dedicated LuxSci Business Class servers.

On August 19, 2015 from 23:00 CDT to August 20th, 2015 at 05:00 CDT, this scheduled maintenance will affect network connectivity — it will be interrupted one time for a period lasting between 15-45 seconds.

Please accept our apologies for the inconvenience. We always strive to have minimal downtime associated with deploys of upgrades, however, some maintenances require small delays in network traffic while the process completes. We only perform these types of maintenances after extensive testing and planning to ensure minimal impact.

Please contact LuxSci Support if you have any questions.

Apache Web Server Updates This Week

LuxSci will be updating Apache, PHP, and openssl software on its dedicated and shared web servers this week.

This will occur in a rolling fashion during the following maintenance windows:

  • Monday: 5pm-8pm ET
  • Tuesday: 5pm-8pm ET
  • Wednesday: 5pm-8pm ET
  • Friday: 5pm-8pm ET

When your web server is updated, you may expected a few seconds of downtime as the apache server is stopped and then started again.

In addition to updating PHP, the primary goal of this maintenance is to upgrade all web servers from Apache v2.2.x to v2.4.x.

Inbound email delays for some users

One of LuxSci’s email filtering servers has experienced an issue this afternoon and this has resulted in some email for some users being queued. This email is currently being processed from queue and delivered… we expect this process to finish sometime later tonight.

The users affected are those without our McAfee-based Premium Email Filtering, but with an Enterprise-level account. Email for these users uses through a number of redundant servers, only one of which experienced an issue. As such, only some email for affected users would have been delayed.

We have recorded the root cause of the issue and are taking steps to ensure that such an event is automatically remediated should it arise again in the future.
