Mail server down yet again

You blame a router failure on the email server going down yet again - do you people have any idea how to run a professional ISP company or not? You used to have a good service, but it looks as though you now have utter disdain for your clients. I am growing very sick and tired of having to explain to my very well known international clients why their email doesn’t work yet again. Can anyone recommend a reliable economical webhosting provider?

Please bear with us as we are replacing a SWITCH not a router.
Our mail services have been very reliable since the last migration and this is a very rare and isolated incident that an entire switch would fail. We have provide up to the minute updates through the entire process.

I do not know what will you call a good service.

We had a 48 port switch failure. We replaced the switch from our stock and had most servers up in a matter of 40-60 minutes after having techs on site.
