Hosting error messages are specialised pages that appear when something goes awry for a website visitor.  The most common error is the 404, or in English, file cannot be found.  By default, when these errors occur with websites hosted by NamesAndSpace (N&S), the visitor will be taken to a simple error page with NamesAndSpace branding.

As of today (11th June), hosting error messages will now be handled through our support website, ACS Support.  For website owners, this change means that the number of steps required to contact our support team is reduced – with the new messages, you are already on our support website.  For website visitors, the context of the error messages remains unchanged.

Messages customised to your site

The majority of NamesAndSpace hosting packages included the  to specify custom error messages.  Hosting customers may be interested in creating messages that conform to their site’s design and/or to their own wording.   If you are interested in configuring custom error messages for your hosted website, please contact our support team who will be able to assist you further.

Our technical support team has recently upgraded the NamesAndSpace webmail.  The new version of webmail is both faster and easier to use.

If you are a standard NamesAndSpace (N&S) hosting customer, you may access webmail at any time.  All you need to know is your e-mail address and password.  Once you have these to hand, open your web browser and go to http://mail.namesandspace.net.

A side-effect of yesterday’s Internet Connectivity Issues was that our backup mail systems were subjected to a near 24 hour real world test, which they passed with flying colours.  All our Backup MXs performed exactly as intended without compromising the service availability for any of our mail customers even when running under loads of tens of thousands of messages.

What’s a Backup MX?

In the event of one of our primary mail servers going offline, all mail traffic is automatically transferred to one of our backup servers, called a Backup MX.  This switchover is seamless and is completely transparent to both the sender and the recipient.  The Backup MX will then store all incoming messages until such time that primary server is online again, at which point all messages are automatically sent to it.

All NamesAndSpace hosting accounts that include mail services automatically come with a Backup MX facility so that in the event of our the N&S mail server going offline, you don’t lose any messages.

Changes to Spam Filtering

At the peak of yesterday’s traffic,  our Backup MXs were storing in excess of 20,000 messages pending delivery.  Needless to say, the vast majority – more than 90% – of these were spam or junk mail.  In light of this, we are revising our spam filtering systems to purposefully intercept and eliminate a substantial proportion of spam messages before they reach individual e-mail accounts.

Our spam filtering systems work on a score-based.  Every message passing through our servers is subject to a series of checks, each of which is designed to test a particular aspect or property of the message for validity.  If a check fails, then the a value is added to the message’s spam score.  Once the score reaches a threshold value – the spam mark threshold – , the message is considered to be a spam or junk message.  If the score reaches a higher threshold value, then the message will automatically be deleted.

The changes we have implemented are two-fold.  Firstly, we have lowered the bar of the spam mark threshold.  This will have the effect of a higher proportion of messages being marked as being Spam.

The second change is more proactive.  One of the checks we employ is called a Blacklist Lookup where the address of the sending e-mail server for each message is checked against an online list of known spamming servers.  If the sender is a known spammer, then the message in question will now be automatically intercepted and deleted.

Since we implemented these changes last night, the amount of spam messages reaching individual mail boxes has reduced significantly.  These changes were not made solely in light of yesterday’s issues as we had been planning to introduce them in the near future.  If anything, yesterday merely served to accelerate their introduction.

False Positives

In the highly unlikely event you may believe that some valid messages are being marked as spam – otherwise known as a false positive – please contact our Support Team via http://www.acssupport.co.uk for further assistance.

As always, if you have queries regarding any product or service supported by ACS Limited, please do not hesitate to contact our Support Team via http://www.acssupport.co.uk.

We’re experiencing a few intermittent connectivity problems with our office Internet connection this morning.  This in turn is delaying some messages being sent to any e-mail address at appliedconsultancy.com.  At present, we believe these issues to transitory and will should be resolved shortly.

These connection issues do not impact nor affect our NamesAndSpace (N&S) hosting servers, nor any of our own websites like ACS Support. All of our N&S servers are located within resilient data centres that incorporate multiple levels of redundancy.

Update 14:35

We’re still experiencing internet connection problems at our office which is impacting on our incoming messages.  At the last count, there were over 3,000 messages still waiting to arrive (95% of which will be spam).  If you have any questions or queries, please submit them via our support website http://www.acssupport.co.uk which remains fully operational and unaffected by these problems.

Update Wednesday 10:00

The internet connectivity issues have now been resolved and all outstanding messages have now filtered through to our mail systems.  If you sent a message to any e-mail address at appliedconsultancy.com it should now be with the intended recipient.  As with out NamesAndSpace hosting accounts, all our e-mail systems utilise Backup MXs (mailservers) to ensure that no valid (see below) mail traffic is lost.

As per our Christmas & New Year Opening Hours, ACS will only be open from 0900 to 1300 on Christmas Eve. After this time, ACS will be closed until the 29th December when our support team will be available to answer your questions.

Please note that we are operating a Remote Support Only service between Christmas and the New Year. Our support website will continue to operate over the festive period, and any submitted tickets will be attended to when we are open.

During the Christmas to New Year period our support and technical team will be performing maintenance work on all of our NamesAndSpace (N&S) servers. Although we aim to minimise interruption to our services, there may short periods where one or more services will be unavailable. To check the status of our servers and their services, visit our live status feed at http://status.appliedconsultancy.com.

Advanced warning of service downtime will be announced on Reload, our Support & Development blog. Reload may be found at http://blogs.appliedconsultancy.com/reload.

Access to our NamesAndSpace (N&S) servers was interrupted overnight due to an issue we experienced with the DataCentre in which they are located.  Our internal monitoring system immediately notified our support team to this interruption, and normal service was restored at around 9:10 this morning.

Our support team will be performing routine maintenance on our N&S tonight between 1800 and 1900 (UK BST).  This is part of our normal maintenance program.  During this time, access to some services may be either impaired or unavailable.

To avoid any potential issues, we recommend to our hosting customers to avoid making any changes to your websites during this maintenance window.  Furthermore, access to our support website may be unavailable during this time.

f you have any questions or queries regarding this, or any other matter, please contact our Support Team.

Over the last couple of days we have been experiencing problems with e-mail aliases and forwards on our mailserver.  E-mail aliases were either being deleted or disabled without any action by either us or customers.

After a detailed investigation, our support team traced the source of the problem to the online hosting control panel, Helm.  The hosting control panel is a web-based management tool that facilitates comprehensive management of NamesAndSpace hosting accounts including domains, website settings and e-mail configuration.

As part of its’ operations, Helm retains an internal record of all e-mail aliases configured through itself for websites under its’ control.  This list of e-mail aliases had become corrupted, and to compound matters, Helm was either deleting or disabling any e-mail alias it did not recognise on our mail server.  This behaviour is not documented by Helm’s developers, nor is it one we would expect any such management application to do.

Once the cause had been determined, our Support Team immediately isolated Helm pending corrective action.  Unfortunately, the necessary corrective measures required us to take our mail services offline for a period of 15 minutes.  Typically, we only perform such work outside of normal working hours and with prior warning.  However, in this instance, the severity of the problem necessitated immediate action and our mail services were taken offline between 14:55 and 15:10 today for the work to take place.

The problem in question has now been resolved and all normal mail services are now running as expected.

We apologise for any inconvenience this interruption of service may have caused.  We are actively working to minimise the risk of this problem from re-occuring.

The Helm Control Panel will remain offline until such time we are certain it will no longer have a potentially detrimental effect on our mail services.  If you require any changes to your NamesAndSpace hosting package, please contact us and we will make the necessary changes for you.

All of our NamesAndSpace servers and their associated services (Web, E-mail, FTP etc) are monitored from 24 hours a day from two separate locations to ensure high availability and continuity of service.  Our support team also performs routine housekeeping and integrity checks to ensure that our NamesAndSpace services are fit for purpose.

If you have any questions or queries regarding this matter, please do not hesitate to contact our Support Team.   Customers who have registered their e-mail addresses with us can simply e-mail support@appliedconsultancy.com with their query.  All other users, please submit a ticket via our support website, http://www.acssupport.co.uk.

Following routine maintenance and housekeeping tasks, we will be restarting our principal e-mail server, Thor, at around 1730 tonight.  We anticipate that Thor will be offline for about 5 minutes.  During this time, some of our POP users will experience problems in sending and receiving e-mail.

If you have any questions regarding this, or any other maintenance work, please contact our Support Team via our support website http://support.appliedconsultancy.com

Update 17:47

A little later than we intended, but Thor has now been successfully restarted and normal service has resumed.
