XWiki down for several hours at a time at weekends?

Hi Is the xwiki hosting site down for hours at a time at weekends? We have found several times that we can't get at the main site or our own 2 wikis, even though we can still ping the host. Seems to be back again now. Tim Tim Chippington Derrick Chippington Derrick Consultants Ltd Tel: +44 (0)1276 508949 Mob: +44 (0)7971 997948 email: [email protected] http://www.chippingtonderrick.co.uk
