Salesforce

Salesforce is always available securely from any internet-capable device anywhere in the world, UNLESS you choose to set security measures so that ONLY trusted IP ranges may access the system at certain times of the day. It's all about choice and flexibility with Salesforce products.

They always advise of maintenance windows which never interrupt daily processes and I have only experienced 1 outage in my 5 years of working with SF which was resolved in less than 10 minutes.

Salesforce is available whenever you need it. Have never had it go down.

All Force.com apps run on world-class data centers with backup, failover, and disaster-recovery facilities. Force.com has had a proven 99.9 percent uptime record for years. Accordingly, I only recall our instance of Salesforce having one unscheduled, brief down time over 6 years. I can't remember for sure, but it may have been due to our Internet Service Provider (ISP) versus Salesforce itself. Also, Salesforce does it's best to keep customers in the loop: Trust.salesforce.com is the salesforce.com community's home for real-time information on system performance and security. On this site you'll find: Live and historical data on system performance Up-to-the minute information on planned maintenance Phishing, malicious software and social engineering threats Best security practices for your organization Information on how we safeguard your data

On the last 12 months scale, I didn't encounter any unplanned outage or application errors. Sometimes the SFMC (Exact Target) is a little slow during noons, but it is understandable. Planned outages are adequately pre-notified on the login and via separate email alerts.

Salesforce does a great job with their scheduled maintenance. I have not faced any downtime at all.

Very occasional outages

Over the past five years we have only experienced one actual downtime whereby the service was unavailable for several hours.

Very good uptime. Planned downtimes are shown well in advance. trust.salesforce.com documents everything publicly.

• Very reliable. Upgrades are generally made at night or weekends. Minimal disruption

In the past year, we have had some downs for searching etc, but our people don’t see it.

No outages that I can remember. Releases, upgrades, maintenance etc are all routinely planned and communicated via email and when logging in.

There have been times when it's gone down. It’s generally not the entire network, but just a cluster.

It is very good. We have just experienced scheduled downtime. At one point they moved one of our development instances and we got 2 months notice. We have never had an issue with system down without prior notice.

It is never down.

For an application this large and complex it’s very good. There have been a couple of down times, but it has never disrupted our business to a major degree. There are only a couple of configuration changes that require them to take your instance offline and that is known downtime. An example, is when we turned on multicurrency.

Very good – almost 100%. With their latest release mechanism, really no downtime.

It has been down before, but not frequently.
