Now that I am again freelancing, I find myself solving unusual issues, many of which had no online solutions.

Given these no doubt plague other developers, let’s share!

As somebody who runs a few sites, I like to keep an eye on them and make sure they’re up and responding correctly.

My go-to for years has been Pingdom, but this year they gutted their free service (update 2021 it's toally killed and now owned by Solarwinds... yeah, the people who got hacked and unknowingly distributed a back door to all their customers) so maybe not that service.
