My web host has just made me aware of some upcoming downtime.

Essential Maintenance
On Sunday 18th (January) we need to perform some maintenance in our data centre in London. This will cause some services to be stopped during the hours of 11am – 6pm. The services which will be affected are:

All VoIP customers on lon-pbx-1/2/3 will be unable to make and recieve calls from thier phones, including any huntgroupsetc, will be unavailable for a period of time during the window of maintenance.

All customers web services running on lon-file-3 (/home6) will be unavailable for a period of time during the window.

Other services may be affected during this time and we apologise for any inconvience caused.

That includes me.  So, no web service during those times (UK times).
