Hi guys,
Sorry for this inconvenience. Our site has come under heavy malicious attack over the past few days. It's not doing any damage, but as our defenses adapt the site may appear offline for some users though it is online for most users.
If you can provide your IP address (post here or PM or email), we'll whitelist you and that should help.
Thank you,

This blog post at cloudflare seems relevant. Perhaps you can ask CloudFlare to tighten up their CSR's lips in relation to your host information, and consider changing your origin host if it's not too complex. Further, strongly consider any previous associations with individuals inside of this community, and any bad feelings that might exist, as some cause for concern.
