Ahora resulta que es DNSStuff quien no me deja acceder a sus servicios por culpa de un ataque de denegación de servicio que viene del proxy:
WARNING: You are using a web proxy (220.127.116.11) that is currently being abused by malware. You should contact whoever is in charge of your web proxy (if you aren’t sure, contact your Internet provider) for assistance. You should let them know that the web proxy at 18.104.22.168 is being abused and participating in a DDoS attack (and may be an ‘open web proxy’), and that they must fix the problem. Searching the web proxy logs for ‘netgeo.ch’ will definitely find the rogue hits (but could possibly find some legitimate hits).
Sorry for the inconvenience, but we are under a DDoS attack, and your Internet provider is partially responsible.
PLEASE NOTE: This DDoS attack is bad enough when we have it under control. This is a free web site. We cannot let the attack damage us further by taking many hours of time responding to everyone about how to manage web proxies. If you do not know what a web proxy is, or do not run one, you must contact your Internet provider for assistance. If you do run one, you should be able to search your log files for ‘netgeo.ch?IP=xxx.xxx.xxx.xxx’ (where xxx.xxx.xxx.xxx is the IP of your web proxy) to find these hits. Our site automatically will de-ban your IP within about 24 hours, so you do not need to contact us to get access again. If you are still banned 24 hours later, the hits are still coming. And yes, we do know what web proxies are, and no, we are not blocking you because a lot of people access our site through the web proxy — we are blocking you because you are providing web access to someone who is running malware that is abusing our site.
Su mensaje es bastante más agradable e informativo que el de Slashdot, lo que me sorprende un poco, y como mínimo me dicen que en 24 horas me levantarán el castigo, a ver si se ha parado el ataque.
Lo que resulta alucinante es que dicen que el ataque proviene de un sitio suizo. Qué complicado que es esto de internet…
