Our mail servers crashed yesterday afternoon due to what
appears at this time to be a local spammer attack. The mail servers are
back up and running at this time, but the webmail applications are not
working. We will be working through the back log of mail today to filter
out the spam and get it injected back into the system.
Tuesday 11:15 am September 28, 2004
One of our core routers crashed this morning when we
inserted a DS3 card into the router. This caused an interruption to the
local network. We have rebooted the router and everything is functioning
as expected.
Tuesday 9 a.m. September 21, 2004
Our primary mail server stopped processing messages
through the anti-spam system last night due to a memory leak. We have
restarted the server and are working with the vendor to address the leak.
The backlogged mail in the incoming queue is processing through the
anti-spam system at this time.
Monday 1 p.m. September 20, 2004
We have installed equipment at our new location in the
Level(3) Network facility in
San Antonio. We are waiting on completion of a Fast Ethernet link into the
Level(3) Network to add this connection to our BGP routing tables. The
projected completion is by Wednesday, September 22.
Monday 3:00 p.m. August 2, 2004
Our connection to Savvis is experiencing routing
problems again. We are in communication with their engineers concerning
why the BGP session is being interrupted at this time.
Monday 1:30 p.m. August 2, 2004
Our incoming links to both our internet connections went
down due to routing problems earlier this afternoon. They are both up
again and we are working with the providers to determine the source of the
problem.
Wednesday 6:30 p.m. July 21, 2004
We lost several of our bandwidth links this morning
causing us to move to a new provider on very short notice. We have
installed new links and are in the process of getting the bandwidth load
balanced. We will be adding additional bandwidth as we resolve some
problems with one link to the new provider.
We reduced the allowed bandwidth per user today to
preserve the available resources. The reductions will be removed later
this evening as the new circuits prove themselves reliable.
Monday 3:15 p.m. June 21, 2004
We have installed the new mail server and it is
processing mail as expected. We are copying the existing mail store over
from the old server at this time, so new mail will come in immediately but
older mail will be in the mailboxes in a few hours. We currently have
webmail disabled because we can't merge the webmailboxes without losing
data. It should be online within an hour.
Friday 1:00 a.m. June 18, 2004
After extensive analysis we have found the mail server is
experiencing a performance degradation in the drive sub-system that appears
to be getting worse. The hardware all reports no errors but the effect is
real. We are expecting to receive a replacement server today and put it into
service over the weekend. During that time the primary focus will be on the
reliable delivery of mail. The spam quarantine and related functions are a
secondary concern as we are trying to reduce disk access until the new
server is in place.
Wednesday 1:00 p.m. June 16, 2004
The mail server is currently overloaded with incoming spam which is causing a delivery backlog.
are working on the problem at this time.
Tuesday 12:00 p.m. June 8, 2004
The web server is back up and serving pages. There is
considerable configuration remaining to be done in order to allow editing
of web sites via Frontpage or FTP.
Tuesday 4:00 a.m. June 8, 2004
The web server is down for maintenance.
Monday 10:30 a.m. May 3, 2004
The inbound mail is currently backed up due to a spam
attack from a client's server that has been compromised. The client's
server has been quarantined from the service and we are working through
the mail queues to delete the spam and recover legitimate mail.

We experienced problems in our core network Sunday
morning related to the Sasser virus outbreak. The volume of the virus
attack on the core subnet was overwhelming the servers and their ability
to communicate with the routers. We resolved have resolved the problem.
Tuesday, 1:00 a.m. March 10, 2004
The mail server has been upgraded with a new version
this morning for better spam detection and resistance to rogue mail
attacks.
Saturday, 8:00 p.m. March 6, 2004
We have just recovered our server from what appears to
be a spam attack from one of our own customers. We are reviewing the logs
at this time and have quarantined a large quantity of mail and are going
through it at this time to determine exactly what happened. The mail
server is now up and the offending customer has been disconnected.
Wednesday, 3:45 p.m. January 28, 2004
Savvis corrected a problem with our connection and it is
now back to full capacity. There was a short outage forcing all our
traffic through Sprint, but connections have now returned to normal.
Tuesday, 9:30 p.m. January, 27, 2004
Our primary web server's motherboard failed around 4:45
p.m. this afternoon and could not be recovered. We have moved the data to
a new server and completed the rebuild. The rebuild took longer than we
would have liked because the new hardware is substantially different than
the original server (different processors, different motherboard, more
memory, bigger disks, etc.). We will continue to monitor the new server to
assure it is stable.
Tuesday, 11:00 a.m. January 27, 2004
Savvis is reporting problems on our connection to them
that is affecting our connection speed. They are working on the problem at
this time. We do still have a connection but it is somewhat degraded in
capability.
Saturday, 12:30 a.m. January 24, 2004
Our primary web server had a serious drive failure this
morning sometime before 10:00 a.m. We have now recovered from the failure
but there are issues with a number of websites we host. Due to the rapid
recovery process a direct restore from tape was not possible without
overwriting other critical information concerning the system. A slower
process would resolve this but would require waiting on hardware that is
not locally available. We will begin the process of correcting the current
configuration to restore all the websites ASAP.
Wednesday, 10:30 a.m. January 22, 2004
While upgrading our mail server to a new version to
provide additional anti-spam functionality we have experienced a failure
in the smtp-auth protocol. The vendor is working on the issue at this
time. Smtp-auth is the functionality that allows a customer on an external
network use our mail system as their outbound server by authenticating the
connection using the customers email address and password.
Update 11:00 a.m.
We are regressing to the previous version to await a
resolution of the smtp-auth problem.
Update 1:30 p.m.
We have upgraded again and installed the latest patch
from our mail software vendor. The smtp-auth problem has been resolved.
