Qiqqa is by far the strongest solution for research and managing pdf's. Zotero, named as a comparison is weak as it does not allow pdf;s to be loaded into its interface - you need to use a pdf reader, which defeats its whole purpose. With Qiqqa documents in a library can be searched together. It has excellent maps of your libraries. It is not prefect, having a few glitches, but still is the only one of its kind.

Statuscake.com if you just need a simple up/down monitor. Source: about 2 years ago
I've had a great time with statuscake.com for my personal and friends sites. They've even improved custom status pages to include an automatically signed certificate too, so you can make a site like status.yourdomain.com... Test TCP connection, specific HTTP/HTTPS query etc. 5 minute intervals for free, more with paid plans. Source: over 2 years ago
I use statuscake.com for external stuff and nagios for internal. PRTG is good too. Source: over 2 years ago
I use statuscake.com for all my personal / friend sites. There seems to be no limit to number of sites to monitor for basic 5 minute intervals in the free account. Source: over 2 years ago
I use noip.com for a free domain name and a free plan on statuscake.com for this setup. Source: almost 3 years ago
