WMAP and Plank are Evidence against the Copernican Principle.
Further evidence against the BB model and in favour of the geocentric model is the article entitled Large-scale alignments from WMAP and Planck
The largest structures in the microwave sky, the quadrupole and octopole, are aligned with one another and with physical directions or planes – the dipole direction and the Ecliptic plane. These alignments, first observed and discussed in the one-year WMAP data, have persisted throughout WMAP’s subsequent data releases, and are now confirmed in the one-year Planck data. On the one hand, this is to be expected: the largest scales are precisely measured and the same CMB sky is observed by both satellites. On the other hand, this is surprising: cleaned, full-sky maps are required to see these alignments, and the removal of foregrounds, along with other systematic effects, makes it challenging to accurately produce full-sky maps on large angular scales.
In this work we have studied the ILC maps from the seven and nine-year WMAP data releases and the NILC, SEVEM, and SMICA cleaned maps from the first-year Planck data release. Qualitatively, the main anomalies detected in earlier WMAP releases remain: the quadrupole and octopole are aligned with each other; the normal to their average plane is aligned with the dipole – the direction of our motion through the Universe; that normal is also close to the Ecliptic plane, so that the average plane of the quadrupole and octopole is nearly perpendicular to the Ecliptic plane. Finally, as can be seen in Fig. 5 which shows the sum of the quadrupole and octopole from the SMICA map, the Ecliptic plane cleanly cuts between a hot and cold spot, thereby separating weaker quadrupole+octopole power in the north Ecliptic hemisphere from the stronger power in the south Ecliptic hemisphere.
In summary, the quadrupole and octopole alignments noted in early WMAP full-sky maps persist in the WMAP seven-year and final (nine-year) maps, and in the Planck first-year full-sky maps. The correlation of the quadrupole and octopole with one another, and their correlations with other physical directions or planes – the dipole, the Ecliptic, the Galaxy – remain broadly unchanged across all of these maps. Consequently, it is not sufficient to argue that they are less significant than they appear merely by appealing to the uncertainties in the full-sky maps – such uncertainties are presumably captured in the range of foreground removal schemes that went into the map making. It similarly seems contrived that the primordial CMB at the last scattering surface is correlated with the local structures imprinted via the Integrated Sachs-Wolfe (ISW) effect in just such a way to generate the observed alignments, as proposed elsewhere (Rakic et al. 2006; Francis & Peacock 2010; Dup ´ e et al. ´
2011; Rassat et al. 2013; Rassat & Starck 2013), even taking for granted the reliability of the procedure to subtract the ISW signal from the map.
Such large scale structure to the universe overturns the Copernican principle and is not predicted by the BB model. Also, according to The axis of evil there have been a number of publications for a preferred axis in the universe.
The homogeneity and isotropy of the Universe – also known as the Copernican principle – is a major postulate of modern cosmology. Obviously this assumption does not imply exact homogeneity and isotropy, but merely that the observed cosmological inhomogeneities are random fluctuations around a uniform background, extracted from a homogeneous and isotropic statistical ensemble. One may expect that the ever improving observations of CMB fluctuations should lead to the greatest vindication of this principle. Yet, there have been a number of disturbing claims of evidence for a preferred direction in the Universe [1, 2, 3, 4, 5, 6, 7, 8, 9, 10], making use of the state of the art WMAP first year results [11]. These claims have potentially very damaging implications for the standard model of cosmology. It has been suggested that a preferred direction in CMB fluctuations may signal a non-trivial cosmic topology (e.g. [1, 12, 13, 14]), a matter currently far from settled. The preferred axis could also be the result of anisotropic expansion, possibly due to strings, walls or magnetic fields [15], or even the result of an intrinsically inhomogeneous Universe [16]. Such claims remain controversial; more mundanely the observed “axis of evil” could be the result of galactic foreground contamination or large scale unsubtracted systematics (see [17, 18, 19, 20] for past examples). A closer inspection of the emergence of this preferred axis is at any rate imperative.

There is also another prolem for BB cosmology, in the handedness of galaxies. Longo in a paper entitled - Does the Universe Have a Handedness? proposes a test from the Sloan digital Survey Data.
Does the Universe Have a Handedness?

I have studied the distribution of spiral galaxies in the Sloan Digital Sky Survey (SDSS) to investigate whether the universe has an overall handedness. A preference for spiral galaxies in one sector of the sky to be left-handed or right-handed spirals would indicate a preferred axis in the Universe. The SDSS data show a strong signal for such an asymmetry. Its axis seems to be strongly correlated with that of the dipole, quadrupole and octopole moments in the WMAP microwave sky survey, whose unlikely alignment has been dubbed "the Axis of Evil"
.
Our Galaxy has its spin axis along the same direction. I propose a mechanism that explains all of these alignments in terms of a large-scale cosmic magnetic field.
He concludes that the universe is asymmetric -
If I maximize the asymmetry by choosing the optimal axis, this becomes an asymmetry of 3.6 σ at an RA of 188°. The probability of this happening by chance is about 0.04%. The SDSS coverage in declination is too limited to say much about the declination other than that it is consistent with δ ~ 0°.

Such asymmetry is contrary to the BB model and the Copernican Principle.
