Republicans don't undo things in a matter of weeks. Obamacare is one example. Roe v. Wade is another.

It takes longer than weeks to plan, but when they enact their plans it doesn't take long. Democrats always play the game of... had we only known they could do that, now our hands our tied. Case in point is when they authorized the COVID-19 pandemic relief and then Trump fired the single person responsible for preventing fraud, and Democrats were like... hmm, we did nazi that coming.

You're cherry picking data to confirm a political bias. I'm not interested in trading counter examples, but if you could provide a scientific source that shows the pattern, that might be actually convincing.

Ah, yes. The classic "all our customers are morons" approach, with no opt-out for those 0.1% who, in fact, are not. Very typical among ISPs/Telcos. Where I am, we used to have a different, "nerdy" ISP [0], where customer was allowed to bring their own modem; they also provided real IPv4/v6 dual-stack since forever, easy to request a /29, tech-support that's realistic to reach, and staffed with people who know what th…

The opt-out is buy business-class service[0]. My guess is that the 2x price increase Xs4all was charging for their plan was a bridge too far for most customers. It's important to keep in mind that the vast majority of people rent their modem, don't know or care what a /29 is, and is calling tech support because the plug is loose or the modem needs a power cycle. Bulk-blocking SMTP happened because open ports are botn…

Most of the time you can get around this by providing your own 'dumb' modem with no VOIP features on it. Quite often the control feature is on the firmware the ISP uploads to the modem.

Even if the provider is stupid AF you can usually get around the residential restriction by starting the discussion with the business side of the company; once the salesman has a nibble he's not gonna cut you free if he can help it.

And then get a 2 year term on whatever seems a "good deal" at the time (I had cable speeds and 5 IPs) and once that is up call them and "drop down" to whatever you actually need (cable speeds and 1 IP) - you'll find that at that point there will be various "packages" that were never advertised but the system is quite capable of supporting.

If all else fails, find a company that works with the provider and offers service over their "last mile".

You'll pay for all the above, but not as much as you might think, and business support is actually good in many, many cases. Fabled evil Comcast rolled a truck twice until they tracked down a problem, at no charge.

That doesn't make what they're doing okay. To see why, imagine that they instead blocked access to all email services except their own, since spam is a big problem.

That's basically what domestic ISPs do. You will probably find that outbound traffic on port 25 is blocked, because all of your pwn3d inadequately-patched Windows machines are spam cannons now.

Yep - some block it so hard you have to use other ports to communicate with offsite mail servers (and why various other ports are found, now).

Some ISPs will remove the block if you ask.

Yep - VPS tunneling usually through nginx is how I get around it for my use cases. Cheers on the co-op ISP - that's outstanding and I wish more places did that. In so many ways that's living the dream!

I've certainly dreamed of a co-op / credit union isp. I think in absolute numbers there are a lot of people who would value that, but only one or two people in any given area, so no way to service them. (Not considering sattelite for both bandwidth and latency reasons.) A long time ago I was in some newsgroup or irc channnel and someone from Russia I think it was, was just casually describing their internet connectio…

You can do something similar in the US - many condos have it setup where they technically are an ISP and pay for transit.

Usually it's not worth it because you end up doing end-user support for every neighbor and people are dumb as rocks. But you'd be surprised how cheap a "very fast" transit internet connection can be.

At least where I am in SoCal, AT&T literally just deployed fiber with plans up to 5 gigabit/s. I'm so glad to be leaving Spectrum behind, because when moving here I never thought I'd have a cable Internet provider that made me miss Comcast...

So hopefully you have some other options soon. :)

My ISP breaks traceroute outside of the network. Their transit is cut out of my traceroutes. Full technical story at https://blog.habets.se/2022/05/Another-way-MPLS-breaks-trace...

Huh, I remember back in the day seeing weird latency cliffs like that when trying to troubleshoot latency issues when playing World of Warcraft. There always seemed to be one between basically any ISP I was connected to and the AT&T network blizzard was running their servers on.

They are probably trying to reduce SIP abuse. It's a big problem.

Glad this is at the top. The linked Reddit thread demonstrates a common but fundamental misunderstanding of SIP. Port 5060 is used for call control and is very low traffic. At most you may have timed OPTIONS messages but a “standard” SIP deployment is at most a handful of (small) packets per second per call setup and tear down with occasional REGISTER messages on an interval measured in seconds. Very low traffic and…

Not the ISP's responsibility.

However the ISP will get blamed by some victims.
