Hi there,

The trusted Sage Cell server stopped loading external resources, e.g. for

load("https://bitbucket.org/malb/lwe-estimator/raw/HEAD/estimator.py")
n, alpha, q = 256, 0.000976562500000000, 65537
set_verbose(1)
_ = estimate_lwe(n, alpha, q)

http://aleph.sagemath.org/?z=eJxNjcEKwjAQBe-F_kPoqYXYjZWkKHgQFPyLkOhii6mJyWrx782hiO84MPOcN9e6GohC2gHYkezrckdqfbzBZJwFN-MKE42TIR8hmhnOp8MRfqgNn6opiwdnxoXBcPZke9ZJxZlohRDbXknVSbGMMyXlpi-LhKTfGK1PWK-zr7O1NFHnz_ov2HwBPwsyhw==&lang=sage

I’m getting

gaierror: [Errno -3] Temporary failure in name resolution

During handling of the above exception, another exception occurred:

Is that a bug or by design (i.e. tightened security)?

Cheers,
Martin

by design. They were hit by spammers and had to disable this.

Minor point: it was very aggressive cryptocurrency miners, not spammers...
