Is it just me, or is the website knackered?

I'm getting the message:
"Couldn't execute query:

select distinct s_id, (s_img+s_links+s_gaz +s_news+s_folk+s_other) as posts, s_children, s_orig, s_name, s_group, st_name, s_os_coord, s_os_index from ma_sites, ma_site_types where s_parent = 198 and s_type=st_id order by s_name.

1030: Got error 28 from storage engine"

when I try to look at ANY site! :(
