Is it DNS, or something else?

Most “the internet is slow” complaints have nothing to do with the internet. These tools measure what a browser can see of your connection and say, in plain English, what they found — and what they cannot see.

Email Deliverability Check

See whether someone can send email pretending to be you

Reads the SPF, DKIM, and DMARC records published for your domain and explains what each one currently allows. Public records only.

Building

Connection Quality

Round-trip time, jitter, and packet loss over real UDP

Measures the transport games and voice calls actually use, rather than ICMP ping, which routers routinely deprioritise. Waiting on a measurement endpoint.

Building

Website Security Headers

Check your certificate and browser security headers

Inspects the TLS certificate and the response headers your site sends, and explains which protections are switched on. One ordinary request.

Why These Exist

We got tired of driving out to find nothing wrong

A browser can only see from your network card outward. That is a real limit, and we would rather say it than pretend otherwise.

We run an IT company, and a regular call goes like this: the internet is slow, nobody can say how, and by the time someone arrives it is working again. Meanwhile the speed test everyone reaches for measures download bandwidth, which is almost never the thing that is actually broken.

So we built the checks we run ourselves and put them somewhere anyone can use them. If a result points at something we can help with, there is a phone number. If it does not, you have still learned something worth knowing.

These tools cannot see your Wi-Fi signal, your switches, or your cabling, and they do not test bandwidth or packet loss — and those cause more everyday slowness than DNS does. So a clean result is still useful: it rules out slow DNS from this browser and points the search elsewhere.

Want someone to look at it with you?

Run a tool, then call and read us the results. We will tell you whether it is worth doing anything about — that part does not cost anything either.

On-site work covers Lawton, Fort Sill, and Southwest Oklahoma. The tools work from anywhere.
