On January 27, 2015, security vulnerability CVE-2015-0235 codenamed GHOST was announced. We don't believe there is any way for us to be attacked by this vulnerability, but out of an abundance of caution we are updating to the latest versions anyways. This requires us to reboot all our servers to load the new version. We will be rebooting all the legacy web servers, pic servers, and data feed servers between 10 PM - 12 AM Central Time Saturday January 31st We will be rebooting a...

Emergency Maintenance

REW Steven posted this 1,778 Views

On January 8th we were informed by Rackspace that one of our cloud server physical hosts is alerting for bad RAM. Our servers use ECC (Error Correcting Code) RAM and can handle a few errors, but when they start to happen, its time to replace the RAM before the server crashes. In an effort to prevent unplanned downtime, we have scheduled an Emergency Maintenance with Rackspace to replace the RAM in this server. We are currently scheduled for sometime between 12 AM and 3 AM Pacific (3 AM - 6...

Server Performance

Morgan has asked me to do some testing on our servers performance to show to our clients. This blog post will contain the results. All test were performed from a Rackspace Cloud Server in the Chicago datacenter to give a bit of distance from our DFW servers. Network Latency The first thing we need to know, is how long does it take internet traffic to get to our servers and back. This is greatly variable on the end users geographic location. To connect to our web servers your web browser ...

LEC 2014 Speed Improvements

REW Steven posted this 1,039 Views

In the new LEC 2014 we've made some speed improvements in the backend to some of the lead pages. These improvements will also be available in 5.0. One of the tools we've used to increase speed is to reduce the amount of data stored in your database. Smaller databases need less RAM to run quickly and will perform better. The first optimization made is to store the History Events for Emails, Saved Listings and Viewed Listing in a more efficient fashion. Previously we stored the full email ...

Heartbleed SSL Vulnerability

On Monday April 7th it was revealed that there is a vulnerability in a popular SSL package called OpenSSL. Full technical details can be found at The bug only affects very recent versions of openssl and only our cloud servers have a recent enough version of openssl to be affected. They have all now been patched. You can use this tool to check if your site is vulnerable (only if you actually have SSL for your site)

Drip Campaigns

REW Steven posted this 1,313 Views

I've seen a lot of questions about how EXACTLY campaign emails work. So here is a full explanation of the algorithm and all the edge cases I can think of. This is based on 4.3 but most of this logic has remained unchanged since 4.0. The campaign mailing job is run once a day. The time of your run is randomly picked so we don't have all customers trying to send at the same time. If it's important to you to send around a certain time of day you can contact support and have your job moved nea...

The Castle Back in November 2012 Morgan and I went and visited Rackspace in San Antonio. They have a pretty cool office; they've converted an old mall into their headquarters. The Castle. We talked about our hosting and how we can continue to grow. They talked to us about a Private Cloud based on OpenStack. But let's back up a second and talk about how our current infrastructure works. We currently have 3 different kinds of servers. Data Feed Processing / Image servers, Data Feed Databas...
