Is wpengine.com Safe?

This is a very popular hosting site for wordpress blogs and websites, I can't find anything suggesting that the host is not trustworthy. One comment says that wpengine is listed on the URIBL, but it seems not to be true sins I can't find them on the list.

I hope everyone here understands exactly what they're talking about. WP engine is a web host they do a first class job. The fact that one bad apple could hurt this entire company is unfortunate but please do not judge the entire host for one of their customers. I have given this link to show you guys that WP Engine was on top of this problem and fixed it right away I think if you read this you will be far more understanding as to why the domain has been affiliated with spam. http://wpengine.com/2012/07/dns-issues-earlier-that-caused-wpengine-com-to-go-offline-briefly-this-morning/?SSAID=389818 if anyone does not feel like clicking on the link that's understandable I have posted the information that you would get from clicking on that link "DNS ISSUES EARLIER THAT CAUSED WPENGINE.COM TO GO OFFLINE BRIEFLY THIS MORNING WRITTEN BY BEN METCALFE ON JULY 17, 2012 Ben Metcalfe, co-founder WP Engine writes… Earlier this morning, our domain ***** stopped resolving for a short time. This resulted in our site, our my.wpengine customer control panel, our status.wpengine.com domain, and some customer sites to be unavailable for some visitors, depending on the status of their ISP’s DNS cache. First and foremost we’d like to apologize to everyone who was effected — although the downtime was brief and was caused by an upstream provider outside of our control, DNS downtime is unacceptable! I’d like to take the opportunity to explain what happened. Some time yesterday it was reported that one of our client’s websites was hosting malware. We host tens-of-thousands of domains, and so occasionally such infections do occur, often when a new customer moves to us, taking their existing malware infection with them. The person/entity reporting this sent emails to the abuse@ email addresses of all of our service providers, including ones that were not involved in the hosting of the infected site. They also sent the report to the abuse@ email address of our domain registrar. Unfortunately, and for reasons unknown, they did not send the report to our own abuse@ email address here at WP Engine. One of our providers immediately forwarded the email to us and we had our independent security partner investigate and clean up the infected account within a few hours of the original report. However, our domain registrar decided to take the entire wpengine.com domain offline — including all subdomains — in order to bring the infected site offline (the infected site was pointing their domain to a CNAME of a wpengine.com subdomain). Unfortunately they decided to do this many hours after the infected site had been cleaned up, and also without checking with us or successfully getting into contact with us. As soon as we discovered our domain registrar was blocking DNS nameserver requests we made contact with them and had this block removed. Initially they actually blamed our DNS provider, which also sent us on a wild goose chase. Eventually they admitted they had done it. As of right now, all sites should be back up online. We are investigating our next course of action, including whether there are any procedures we can improve on our side, and ultimately whether we need to change domain registrar. We will keep you posted, Many thanks for your understanding, Ben” posted by Thomas Zickell

The domain wpengine.com, registered through REGISTER.COM, INC. is listed on at least two SPAM blacklists as of today. This does not necessarily indicate that they are guilty of sending SPAM, merely that the server that their IP address is associated to was confirmed by at least 2 sources to be a gateway for SPAM. This leads us to recommend caution on this server as it is possible that if it is compromised for SPAM, other data could be compromised.
