Instantbird 1.0 has been very quickly downloaded over ten thousand of times. In fact, it happened so fast (especially immediately after we have been featured on lifehacker) that our server couldn’t handle the load.
We have very quickly been able to mirror our main website on another server, which allowed people to keep discovering and downloading Instantbird 1.0, but we had to close the add-ons website for a while as the load it couldn’t handle was also putting down other services that we really needed to keep online, especially our bug database.
We have tried to re-open the add-ons website at a quieter time, but the server was unresponsive again within half an hour. This morning we tried to improve the website’s performance by adding some caching mechanism and reopened again (at a time when most Americans are asleep) for a try. Again it fall down.
Some people very kindly offered help and proposed to host the website on their server, but it’s difficult to trust someone we barely know to host a website that requires our SSL certificate.
