It was just brought to my attention that the email-to-SMS service was not working. It seems that in the network reshuffle I did last weekend, I forgot to open port 25 (SMTP) on my firewall: this is now corrected and email-to-SMS has now resumed. My apologies, and sorry for the delay; suprisingly it took 5 days before anyone complained :). On a more positive note, the internet connection has been very reliable since I made the last changes.

The changes to our network structure have now been made and hopefully things will now settle down. Pings to the outside world are about 1/2 what they used to be, and are seemingly stable. Naturally, we will monitor the situation, but in general I expect the service to be back to full capacity again. Thank you for your patience and feel free to drop me a line if there are any further problems with down-time.

As you may have noted, the server was moved a couple of weeks back in an attempt to improve reliability. Previously most of the outages had been due to failures on the behalf of the internet provider I was using, and therefore I moved the server in an attempt to simultaneously change provider and add a 'backup' internet connection should the first connection fail. From this respect, the move was successful. However, a side-effect of the move was that the server is now connected to the outside-world via a couple of 802.11g links (don't worry, I'm using 128bit encryption and MAC address filtering to protect your privacy). Sadly the links proved to be slightly unreliable and over the last week there have been various short outages (generally no longer than a couple of minutes) when the link went 'down'. I have therefore spent most of today and will continue tomorrow in reconfiguring the internal network. Once the system is complete, there will be 4 redundant routes from the server to the outside world, each following a different physical route. I hope you will bare with me whilst these changes are made, and promise a much more reliable service as from tomorrow evening at the latest.
