Gotta say I'm mystified by the people who don't think Bluehost servers go down versus those who think it happens all the time.
My own experience -- signed on two weeks ago, with a big complex website to migrate from a host that has had big server outage problems and corrupted or absent backups, repeatedly (dotCanada). Things were okay on Bluehost for about a week.
Then -- every day around 5 or 5:30 p.m. Pacific time (I'm in the Yukon Territory in Canada), that'd be 6 or 6:30 in Utah, sudden gross slowdown or total loss of connectivity. I've been editing the site steadily in cPanel X so it's fairly obvious when it hits -- all of a sudden I hit the save button on an editit page and nothing happens!
Just did a ping thru network-tools.com and got 50-52 ms for the IP (box 140) -- but still can't bring up my site or cPanel.
When I queried the problem through the help center several days ago, I was told it was due to a local power outage (that evening I was unable to connect for between one and two hours). From the funny timing above, I could almost believe that -- right at the hour when the locals get home from work and turn on their air conditioners, electric stoves, etc.
But don't big hosting companies like this one have diesel generators backing up their show? I mean, if every day at suppertime your servers start going down you won't stay in business too long, surely.
What bothers me is the ambiguity. If I know what's going on, and its being fixed, I can live with it -- unless it happens repeatedly as in the case of dotCanada. But I'm not sure what the real story is here . . .
