caligula will be brought down sometime this evening for disk replacement. The subsequent downtime will take several minutes, and will bring down all websites hosted on caligula, as well as e-mail. However, no e-mail will be lost in the transition.

One of the disks in caligula’s RAID1 array is failing. Replacing it will actually only incur a few minutes downtime and with no data loss. However, the server’s performance will slow for a few hours after the downtime as the disk is re-added to the array.

More precise information will be added as it becomes available.

Update Jul 08, 2009 3:44 PM: Downtime is over. Failed disk has been replaced and the array is rebuilding.

Update Jul 09, 2009 11:22 AM: Array has finished rebuilding, and operations back to normal.

Rhombic Networks changed it’s name from Nabla Design in fall of 2005. We’re lapsing our use of this domain name in 2008.

We’ve made void all nameservers and DNS records. If you were using the nabladesign.com domain, any of your services depending on it (such as DNS, e-mail, etc) will soon stop working.

If you need any help transitioning over to the new domains please contact us.

Earlier this afternoon our datacenter was having internal network connectivity issues, preventing access to caligula for several hours. All issues have now been resolved and all services should be working as normal.

You may have received errors trying to send e-mail through Rhombic Networks’ SMTP servers earlier this evening. This problem has been since rectified and all services are back online.

For about an hour earlier this evening the authentication system for IMAP and SMTP connections was malfunctioning. You may have received a “Login failed” error during this time when trying to receive or send mail via Rhombic Networks servers. The problem is now fixed.

There should have been no mail loss associated with this event.
