Luckily I moved my "bread & butter" site from WH years ago (to Pair, which has been flawless).
I still have a reseller account with WH for smaller sites, which are still important, but not my livelihood.
They have only delivered poor support and plenty of downtime. I'm moving that reseller account now, as different sites come back on-line from Westhost.
While tarring the files, I have noticed that the servers are horribly slow, even after coming back on-line. I spent 4+ hours last night waiting on a site to archive, which took less than one minute to decompress on the new host.
There are still major issues at WH, I feel this is far from over.
