By now, I'd guess Dreamhost has around 1,500 servers or so and I believe they add at least 5 each week.
If a unique server were to explode every single day, in order, you'd go over 4 years before the same one failed twice.
Of course, it doesn't work that way, but it should put it into perspective why the status site lists so many failures. Especially when compared to hosts that either don't announce failures (most?) or those that are small and only have a server or two.
Save up to $96 at Dreamhost with ALMOST97 promo code (I get $1).
Or save $97 with THEFULL97.
