IP address blocked on BT DSL Checker


[link to this post]
 
I was playing with multi-threading a python script I use to batch check the BT DSL checker for addresses in postcodes near me and/or fed by my exchange/cabinet.

Multithreading was a success but it looks like I pushed the limit too far and got my IP address blocked on the checker as all it says now is "We are sorry but the checker is unavailable at the moment. Please try again later." It works fine from my other internet connection.

Any of you other "kids" out there using scripts on the BT DSL checker had the same? I'm just wondering if its a permanent ban or a temporary one ...

HAHA, yeah I can no longer do batch check lines either.

They now block IP's when they detect you using macros or checking too many within a set time.

If you don't have a static IP just reboot your modem/router to get a new IP, just don't do any more batch checks.

Read section 3 Use of the Site
https://www.btwholesale.com/pages/static/terms-of-us...

I use to be able to check thousands of addresses with my app, I had to add a few seconds delay between checks, which was fine for ages and around October/November 2015 they started to block IP that was buck checking.

TBH, I don't blame them.

I have a block of fixed IPs so no big deal, at least I now know not to let the script loose on it with any of the others smile

This doesn't make sense as followthatpage.com isn't blocked.

Not sure what metric/algorithm BT are using to detect it but they definitely are blocking at IP address level for some scenarios.

Nice to see BTO blocking attempts for the public to see how shoddy an area is for connections.

Current on Zen, getting around 5mb down - .8mb up
Exchange is Fibre enabled, Cab not economically viable to upgrade - though 'Now Exploring Solutions aka we want someone else to pay for it.'

At the ISP Forum last month one of the slides included:

Broadband Availability Checker (BBAC) -General
GUI Usage
•Increasing volume of hits sometimes excessive levels in one day, automatic blocking of IP addresses to protect service quality


They also said

New Look
•As part of SoGEA and NGA2 developments the GUI will change its layout
•Aim to reduce amount of foot notes and make it more tabular

Understandable but a shame as it shuts down one of the few ways for small communities to glean "accurate" data for their own area.

In reply to a post by BatBoy:

That site is requesting the same address, and not 25,000 with a couple of seconds in between requests, and also those are not for every address on the same cabinet etc.

All I know is several times now I have tried to check 12K addresses and it gets about an hour in so about 700 to 800 addresses and they block my IP.

So I basically gave up.

I might re-write my app to request required addresses over 35 cabinets in a completely random order and see if they ban the IP then.

Or maybe increase the delay to a random range of 10 to 15 seconds.

I am wondering if the BTOR Where and when page has any throttling checks.

The blocking happens after within 1 hour and not a day.
