We’re too Popular!
David ShorthouseYou may have noticed that the EOL site has been flaky at best since approximately 12 EST this afternoon. Although we are serving the site from a load balanced cluster of several machines, we are experiencing phenomenal loads.
I just churned through the web logs from web machines in this cluster and there were 5.8M hits in the span of 3 hours. Most of these happened within 1 hour. We were down (and continue to experience intermittent access) for a few hours, then flipped the machines back on. Since then, there were an additional 5.7M hits, totaling 11.5M hits since 9AM this morning and it is now 2:45PM here. Wow!
We are working hard to resolve the issue so stay tuned and please have patience! I’ll post updates here as the day progresses.
Update Feb 27 @ 11:45AM EST:
In the first 24 hours (minus the approx. 3-4 hours we were completely down) there were:
18.5M hits, 13.3M page views, and 940GB of data transferred.

Tremendous effort! I can’t wait until your site works! This may be preaching to the choir, but perhaps you guys and gals might have planned for more scaling and content distribution before eol.org was so widely announced? In 2008, is round robin DNS with 4 IP’s the best that WHOI can come up with? Back in the nineties moderately busy sites frequented mostly by consumers with dial-up accounts would have 100+ servers behind Big-IP’s and Cisco Distributed Directors. What about setting up topology-based load balancing with other .edu’s around the country, as well as locally distributed? I assume you are doing analysis as to what *exactly* (http requests or sql queries, etc) is responsible for choking your servers? Or how about Amazon EC2 until you ramp that up?

First of all, we’re at the MBL (Marine Biology Laboratory www.mbl.edu), none of us are associated with WHOI, they’re down the road.
Second, we’re actively looking into mirroring, but the project is just starting and hasn’t even staffed up fully yet, so doing more than a local cluster simply wasn’t feasible for this release. I’m hoping we’ll have something lined up for this in the next six months.
Third, it’s not the computing hardware that’s causing the problems, what we’re seeing is a series of networking issues that due to their distributed nature is taking us some time to sort out. We’re hoping to be able to have a more stable environment up soon. I also want to make a public thank you to everyone working overtime on this, especially Pam.
And finally, a clarification for all of you who have gotten this far - we’re hearing people saying we’ve had millions of visitors - please be aware that this isn’t the case. We’ve had 18.5 million hits but every page view has a number of hits associated with it due to the aggregation that we do, this can be as many as 20 for some of the more detailed pages. I keep being told it’s nice to be popular.
Thanks for bearing with us as we get things sorted out.

Asterix Obelis: On the one hand, we are overjoyed with the public response. In effect, this launch is a real test of what loads we would expect. As stated by Jennifer Schopf, we have a complex networking issue going on because our harware appears not to be the problem. We did manage to do some load testing prior to launch but the network loads exceeded our expectations by an order of magnitude.

Sincere congrats, guys! I’m excited! An order of magnitude more traffic than expected is certainly better than an order of magnitude less….no matter the transient down time. Keep The Faith! I know that I will….
