Slammed is a good word. We certainly did get slammed. The good news is that Rackspace.com was able to respond to a RAM upgrade request quickly and between the time I got the alarm about the site availability through diagnosis, upgrade order, installation and restart was a bit under an hour. After some additional system and apache tuning, we were back on the air by 11:45 and have been serving the load since then.
I apologize to those whose requests were not served this morning due to the spike in demand. We've upgraded our service now and we invite you back to check out the NASA software.
The site was dead this morning after the initial slashdot posting. After some quick RAM upgrades by Rackspace.com and some apache tuning here, we've been back on the air since about 11:30 this morning.
I apologize to all of you who wanted to visit the NASA software but were unable because of the spike in requests. We've upgraded the service and are now handling the load so please come back and see what the NASA COSMIC software announcement is all about.
The good news is that we're back on the air. Apologies to all who were not served because of the sudden spike in requests.
More good news in this situation is that Rackspace.com was very responsive in getting a RAM upgrade installed quickly. From the time I got the alarm that the site was down, to the diagnosis, ordering the upgrade having the RAM installed and the server restarted was under an hour. Thank you to all the folks at Rackspace. When the machine came back up, we did a bit of Apache tuning and we've been ok since. The load on the server spiked to 80 before it stopped responding to commands. After the RAM upgrade and tuning, we're down to around 30 with no swapping. (OK, I just noticed a little swapping) Sorry for taking so long to get a response to this comment.
Again, I apologize for not being able to serve all of the requests initially. Please take a few minutes to revisit the site and take a look at the NASA software and the other scientific and academic software.
