What's New?

January 24, 2008
As planned, HVCN was down for two hours for an upgrade of the hardware and a general update to the software. Details of the upgrade and update are posted on the upgrade page.
January 18, 2008
HVCN was unsvailable for 15 hours from 11PM Thursday until 2PM Friday, due to unexpected networking problems. We apologize for any inconvenience that this may have caused.
September 23, 2006
HVCN was down for five hours this Saturday, so that power could be reconfigured in the computer room. It returned to service earlier than expected, at 12:45 PM.

Comcast has not blocked our email since we adopted our policy of not permitting forwarding of fixed email aliases to comcast.net addresses. We are hopeful that Comcast will not impose any further inconvenience on HVCN users with comcast.net email addresses.

September 3, 2006
Comcast has not replied to our phone message. If they do not work with us to resolve this problem, it is out of our control. We did some research and found that Comcast has been blocking many sites all over the internet. This should be of concern to to Comcast customers who rely on Comcast for their e-mail. We have today reluctantly adopted a new policy of not accepting comcast.net email addresses for aliases on HVCN, and we have notified all affected HVCN users. Concerned Comcast customers should review our policy page for more details. We will continue to leave phone messages at Comcast in the hope that they can work with us to resolve this situation.
August 29, 2006
Comcast has initiated a new policy of blocking mail from HVCN, as part of their spam filtering policy. We placed a call to Comcast late on the evening of Aug 29, when we realized that their normal automated system for removing such blocks were no longer working. This represents a policy change of significant proportions on Comcast's behalf, and it affects all customers of Comcast that rely on HVCN to send mail, either by aliases for domains that we host or by mailing lists that we host. We are anxious to work with Comcast to have them remove this impediment, and we are waiting for them to return our telephone call.

HVCN was down for 3 hours this morning so that new software could be installed. The process of upgrading software on HVCN is very difficult, because there are so many things that can go wrong.f one is not very careful. The details and motivation for this upgrade can be found on our upgrade page.
June 9, 2004
HVCN's unix-based server suffered a kernel software failure, causing it to shut down. This was the first such failure in almost two years of continuous operation. We are proud of our reliability record. Because of administrative problems, we could not gain access to the server on June 8 so that we could reboot it. Therefore the server was down for more than 24 hours, from 4:05 PM on June 7 until 9:15 AM June 9. We apologize to all the organizations that were affected, and we thank you all for your patience.
March 8, 2003
Dozens of links were refreshed in the Media Infocenter, bringing it up to date for all of the ownership changes and web sites that have changed or been created since the last time this was done.
August 30, 2002
HVCN has added a new facility to simplify collecting server statistics for your organization. Server stats since January, 2002 may now be filtered. Just go to the Server Statistics Page and select the month. You now get the option to specify a filter. If you don't, you will see the full statistics for the server, but if you specify the server directory used by an organization, the Directory and Request reports alone are showed, and only records within that directory will appear. This results in a much more focused report and we hope it will be easier for everyone to use. Please send comments and suggestions to webmaster,
July 3, 2002
HVCN was off the air Tuesday July 2, and restored to normal service around noon on Wednesday, July 3. During this 36 hour period of unplanned downtime, another round of software updates was applied, and a number of recently announced security holes were plugged. For details see the security upgrade page. We regret that more notice could not be given, to our users, and we apologize for the inconvenience.
