Adobe BC/Web hosting guaranteed up time

No one will, no server can promise you 100% up time, or not expect issues. When you have a DDOS attack for example then issues will happen, if networking routes around the web go down and people can not access your systems then there can be issues with your net but it may not be what your accessing.

That said BC is on amazon infrastructure now so you can google and read up about those services for more information if you like.

BC has had some ropey performance issues of late and a DDOS attack (see the blog) but it did not take BC offline (which other attacks have in the passed) fully so BC have done a good job over time putting things in place to handle that. There are some big sites on BC.

BC uses an SQL server and is .NET based but you do not have access to any of that directly, you do not do any server side code on BC.

In terms of the campaign stuff - BC uses a lot of variety of methods to ensure email delivery, but again this is open to many factors that are often out of their hands or involve 3rd party communications. Things like someone using BC to just SPAM can cause a certain network company to just block and blacklist the whole lot as happens with many campaign systems, but just like other companies BC works to resolve such issues asap as they occur. BC also deploys systems to help stop things being blacklisted or treated as spam, so on times of high web traffic BC will slow down a campaign and trickle that out a bit slower to avoid issues etc.

Overal pretty good is your main answer and this is Adobe, it is not a small company with 3 servers in their office running in a room with a fan.

Adobe do not post that. That is ONE site system and you could pull up similar data from 3rd party sites for businesscatalyst.com.

The problem with that is BC is not like that, a SAAS system that runs through amazon infrastructure across multiple data centres globally.

BC has a status page for information: status.businesscatalyst.com

Amazon has its data http://status.aws.amazon.com/

And since BC is linked to your adobe ID to login, the admin and login service depends on the Adobe creative cloud: Creative Cloud Status

Multiple systems, globally.

One persons site may be down due to many reasons while others on BC will still be up. One Data Centre may have a DDOS attack but Australia sites are unaffected.  BC could offer and article and could offer more raw data if you contacted them directly, but one sites uptime on BC can be different to another on BC.

You have examples of similar software uptime info?

BC is not a hosting service though and your just linking hosting sites.

You understand what BC is and you can not just put your own server code and system on it?

It is not a hosting service.

Hosted solution means that you do not need to host the CMS yourself on something like you have shown. But it is not hosting, lots of people make this misunderstanding so that is why I raise it.

You probably aware that it is NOT just hosting, you can not put your own database, server coding or other CMS on it, it is a SAAS CMS - Software as a solution system.

It's email system is 3rd party so dependent on that, it uses its only campaign system, CRM etc. As part of this it has hosting.

The login system for partners/developers uses the Adobe ID Creative cloud system, but clients do not.

It is under the amazon infrastructure so in terms of where it is hosted that is based on which Data Centre the site is on. So AU Data Centre may have issues like it did on Saturday but US will be unaffected.

Emails may not be working as they are 3rd party system, but sites could be up and running.

Admin runs differently from the front end cached websites so the admin can be down but the front end can be up.

So you could say 95% front end up time for US, but then a different value for EU and AU DC. Then you could have different values for the emails, email campaigns, admin and as a developer the login.

I am sure if you contact BC directly, via the website for example rather then through live chat you could get some other form of information but your not going to get a server status uptime stat like just a hosting company, because it's not, there is more to it.

Yep Patrick

You think the term Hosting is a hosting service.

BC is NOT Just a hosting service. You can not not buy some storage space. It is a hosted CMS solution but do you see anywhere you can just buy hosting space?

So I do not understand why you are arguing that. If you are trying to use BC just for hosting your wasting your time and money and you wont be able to, as I have mentioned just put other systems etc on that.

If you are looking for an all in one solution for an online business or as an agency to build solutions and websites for online businesses - awesome, but you need to understand that this is more then just hosting.
And in terms of that, what I have mentioned is the case with different systems, data centres etc. BC is not just in one place and because it  is not just a hosting company it's setup differs.

I do not know what more to say, if you do not want to understand this from people like myself or what BC tell you then BC may not be the right solution for you and I would recommend go with one of the hosting offerings you have linked and use that as you need to.
