Had a small outage last night. Problem was caused when an automated backup took up all the hard drive space and didn't allow the server apps any room to run.
We have 250gig dual hard drives which had allocated 64gig to the website. This allowed the rest to remain in reserve if needed, expanded the site to 128 gig and rebooted which brought the site back online. Also cleaned out the old backups which brought the site used space from 64gig down to 10gig. So there is 110gig extra space and another 100gig in reserve.
Please let me know if there are any issues, will be tweaking the alerts and stuff to try and catch something like this sooner.
