The hosting company that I have used since the early nineties threw in the towel recently and sold out to another company.
For bloody weeks now they have been slowly migrating email accounts. This week they were due to move the sites, this one scheduled for tomorrow.
Imagine my surprise when the site went tits up earlier. The support from the new company has been questionable so far.
Anyway, sorry for the disruption, let's hope this is the last of it for another 20 years.
