Mail backlog being delivered
As of 6 PM, Thursday, August 21, there are 1.25 million messages in the
email queue awaiting delivery. We are estimating that all backlogged email
should be delivered by Friday night/Saturday morning at this time.
Processing this much email is causing some Chebucto services such as
Webmail to be slower to access than usual. In a related issue Chebucto
text service mail users reported problems sending mail this morning but
this was fixed by lunch time.
Earlier this week the Chebucto main server began mysteriously shutting
down for no readily apparent reason. The main server, which sorts mail,
controls user mail access, and hosts most of the Chebucto Community Net
website, has been in stable use since 2003. The problem was determined to
be from overheating CPUs and was fixed Tuesday evening with additional
refrigerated air being piped directly to the main server.
Since then, a backlog of email, 1.35 million messages at its peak early
Tuesday evening (August 19, 2008), representing around one day's volume of
email, has been delivered as fast as it can be processed. An increase in
incoming email both yesterday and another increase from that again today
has added more mail to the queue to be delivered. By dawn today
the mail queue had dropped to 650,000 messages when mail started
coming in faster than it could be processed. The mail queue grew to
1.33 million messages before some additional server adjustments increased
mail processing speed to go faster than the rate of incoming mail.
In a typical day, 3,000 to 7,000 messages are legitimate email and the
rest of the 1.3 million messages are junk mail, with around 5,000 to
10,000 virus-laden emails thrown in for good measure.
Incoming email is scanned for viruses, scanned to determine if the message
is junk or not then it is sent on to Chebucto's main server for delivery.
Volumes of spam mail have been doubling and sometimes tripling every few
Plans are to replace the Chebucto main server with a more powerful 4 CPU
Enterprise-class server we've had donated to us sometime in the near
UPDATE 16:30 Friday, August 22: The mail queue is down to 170,000
messages from yesterday's peak of 1.33 million. Thanks to the hard work of
Johnathan Thibodeau, Chebucto's main server has processed close to two
day's worth of mail in one day, keeping up with new incoming email while
steadily chewing through the backlogged mail from earlier this week. At
the current rate of processing all mail should be delivered by later on
Chebucto Wireless update!
Chebucto Wireless is online.
Hardware to construct wireless nodes is on order and a number of node host
candidates will be contacted in the next few weeks about becoming live
The Chebucto Wireless project is an ambitious design to bring secure
low-cost high-speed wireless internet access to Metro residents. There
has been interest in the project from community nets and other groups
There has been zero development money from any outside source. All work
on the wireless project has been in addition to the regular technical
maintenance that Chebucto requires to keep operating.
The Chebucto Community Net now brings non-profit high-speed Internet
to the metro Halifax area with a mesh network of wireless
nodes hosted by users themselves.
Chebucto Wireless offers free public access to local metro and
government websites and full Internet access to Chebucto Plus level
memberships, currently $100 per year for individuals.
The areas to be served by the new wireless access will be determined by
the residents of metro themselves. There's a map here.
Chebucto is looking for residents able to host wireless nodes, the
cornerstone of the network, and when we get enough nodes in a
neighbourhood, we can look at bringing network access where it is needed.
A node sign-up form is online

The Chebucto Office does not recommend using the Internet Explorer web
browser for any use except for accessing Microsoft's own Windows Update page. The
popular web browser has been repeatedly successfully targetted by virus
writers in particular seeking to break into home computers to use them for
criminal purposes such as sending out spam, sending out viruses to break
into other computers and being used to disrupt services on other computer
After many reports
about vulnerabilities for Microsoft Outlook and Outlook Express email
programs, and the constant stream of user complaints about randomly
altered program settings and difficulty using the program, the Chebucto
Community Net Office and the Chebucto Technical Committee recommend our
users do not use either Outlook or Outlook Express as their email program.
Keeping Microsoft Windows up to date is also very important. Windows XP
users should have Service Pack 2 installed. All Microsoft Windows users
should make a point of using Internet Explorer to visit the Microsoft
Windows Update site
at least once a month and download all critical updates.
