The npmjs.org website was unavailable for about 10 minutes this morning while our master Redis server failed to save its data to disk.
This is a repeat of the previous outage on April 20
. IN response to that outage, we had already built a replacement Redis host which will not exhibit this problem, and are switching over to it presently.
While this switch occurs, we've temporarily changed our Redis configuration to not crash when it fails to save to disk, and resized the problematic instance up once again.
