Avoid! Nativespace are blocked by more & more servers

I've had over 10 websites hosted at Nativespace since 2007.
I used to recommend it to everyone as the customer service was excellent and the servers were fast and stable.

Unfortunately this has all changed over the years and Nativespace had become one of the worst ISP-s.
I have now left Nativespace and migrated all my sites to different providers.

Here's why:

- Every now and then Nativespace IP-s get blacklisted by spam filters.

- The uptime is ~70%. In the last 3 months there were hardly any days when my servers didn't go down, sometimes for several hours.

- Paypal IPN callbacks are blocked on some of the servers. If you are thinking about selling something on your site in the future, I recommend finding a different provider.

- Nativespace customer support refuse to notify you when your server is down. They do not notify you when they reboot your server and it is down for several hours.

- The "Enterprise Backup" promise is a lie. They had several "catastrophic failures" in the last few months and they had no backup to recover the data from. In the T&C they state that they take no responsibility for data loss and you are responsible for making your own backup. Still, they don't let you set up an automated backup as it would "slow their servers down"

- Emails. The SSL setup is terrible. Every time they migrate you to a new server (which happens quite often as their servers get overloaded), you need to go through the mail setup again (on your iphone, mac mail, outlook, blackberry, ..etc) - as their server name changes. If you want reliable email - I recommend using a different provider.

- Database connectivity. The number of simultaneous connections is capped to 5. I'm sure you know what this means. If your site uses a database (wordpress, joomla, drupal, ...etc.) and you have a lot of visitors - sadly some of them won't get to see your site, they get a nasty database error instead.

- Newsletters. Thinking about sending out a newsletter to 500 people? 300 will go out, then the mail server will block ALL emails for 60 minutes. Spam protection, apparently. Want to send out 3000 emails? No problem, as long as you are happy to write a script that does it for you over 10 hours.

- Is your website hacker-safe? With Nativespace it doesn't matter. You are on a shared server. If any of the sites get hacked, you are likely to get hacked, too. One day your websites are up and running, the next they are replaced by religious messages and x-rated pictures. Sorry, no backup, "our backup server hasn't been running for the last 3 months" says nativespace.

- Blacklisting. In order to avoid DOS attacks, Nativespace aggressively blacklists IP ranges so that your site will not be available from those locations. Unfortunately this means that the visibility of your website is drastically reduced.

Real shame, Nativespace.
You guys used to be brilliant.

For anyone trying to find a fast and reliable ISP - keep looking guys, Nativespace are no longer the right choice.
