See this post for an explanation of why some Merchants may have been unable to access the e-junkie.com website last night:
Note that buyers should not be affected; it's just that the defensive countermeasures we installed last night were blocking some Merchants from using our site (e.g. Admin pages) as a side effect of blocking would-be attacker IPs. We are working on a solution to prevent that sort of inadvertent blockage as well.
As you may notice from the date of the posts prior to yours in this thread, we haven't had a real outage since Spring 2008. This is because, since that time, we have made comprehensive upgrades to our server architecture, such as moving our equipment into a high-security, "top-shelf" datacenter where we have a rack with ample room to hook up as many redundant, load-balanced server CPUs and other equipment as we may need to meet capacity demands. There is no single "main E-junkie server" nor other single-point of failure; if one CPU should happen to fail, that capacity would be taken over by the other equipment, and other hardware has a bypass mode in event of a fault to exclude that unit from the system automatically without a hitch.
The only real difference in our standard JS buttons vs. non-JS buttons is that the latter open the cart in a popup window/tab rather than using the nice cart overlay screen; order processing works the same for both versions.
We do have a 24-hour emergency hotline voicemail number to report the unlikely event of an outage (or any other apparent/pending lapse in service, typically due to an urgent billing situation), listed here:
Calling that line notifies senior staff who are able to take action in case of emergency, so as soon as you leave a message there, someone in a position to respond can evaluate the matter and take action forthwith if necessary.
