In case you never hear from me again – Web server issues

Dear readers I attach a just received email from my web service provider:

Dear Client,

As your website is hosted on our server, you may well be aware of some on-going issues with sending e-mails to Microsoft account holders (Hotmail etc.). We recently decided to move to another hosting company and have now got in place a new dedicated server for all of our client accounts.
The websites have all been copied across to the new server and tonight we will change the name server IP address to point your domain to the new server.
This will be done late tonight, during low traffic times, to avoid any impact to your business. This will remove any IP black list issues and all e-mails will work as they should.
There will be some down time while the DNS propagate around the internet. This should not be more that a few hours and may be much less.
This is unavoidable I am afraid.
MORE GOOD NEWS!
However the good news is that the new server is faster and more modern than our last offering. It is also located in Europe and so load time will be faster.
We have also (at no additional cost to you) installed the latest Spam eating software on the server, so you should see significant drops in the amount of spam your receive. This is called ‘MagicSpam’ and blocks spam before it is sent to your own account. Spam was the cause of the last IP Black listing fiasco and so to avoid any repeat performance, we have set the spam setting to fairly aggressive.
IF you are notified by somebody trying to send you an e-mail, that they cannot (they will know as a bounce back with the reason will be sent to them), then please notify us and I will ‘white list’ their address.
SOFTWARE UPGRADE
As part of the server upgrade, we have also upgraded the software that the server runs and have tested over the past week to ensure functionality of your website is maintained. We have made tweaks to the code where required – free of charge. However with any move of this nature, there may be some small issues with your website once the move is complete. So please can I ask that you also test your website and let me know of any issues you find.
PLEASE ACCEPT MY APOLOGIES FOR A SITUATION COMPLETELY WITHOUT MY CONTROL AND NOT OF MY MAKING.  IF YOU ARE TRYING TO CONTACT US AND HAVE NOT RECEIVED A REPLY PLEASE DO TRY SKYPE “bellaugello” or email drummonddom@mac.com  BOTH OF THESE ARE UNAFFECTED BY THE ABOVE PROBLEMS.
